* Created 3rd slider-page on creating project steps which is used
  to select appropriate plugin, processor type, plugin GUI template,
  other options.
* Created plugin GUI templates system;
* Created some plugin GUI templates for GenericEditor;
* ButtonGroupManager and TiledButtonGroupManager classes minor
  improvements and fixes;
* Changed index of ProcessorType::UtilityProcessor;
* Other minor bugs fixes.

* Added template for creating appropriate JUCE GUI component which will
  be automatically created inside plugin editor.
* Some improvements to the editor plugin template due to the addition
  of GUI component inside it.
* Added possibility to change desired with of the plugin in the config.
* Some minor improvements.
* Some stylystic fixes.

* Added ParametersEditor;
* Some improvements of Parameter class;
* Added possibility to generate code for parameters;
* Added possibility to save/load parameter in the project file.
* Other major and minor improvements.

Refactoring.

* Fixed some problems with build due to the symbol redefinitions (It's
  still need to be reviewed and we need to find a better way for doing
  this);
* Added plugin properties in the configuration and adding the
  possibility to change it on the fly (still WIP);
* Added visual component to select the appropriate tab in the plugin
  configuration;
* Some cleanup;

* Added template file for the RecordEngine plugin type.
* Changed a bit structure of other plugin template files.
* Added missing functions for some plugin template files.
* Fixed some bugs with OpenEphysLib.cpp file template.
* Typos fixed.

* Added template files for FileSource and DataThread plugin types.
* Minor stylystic fixes and refactoring for some FileSource plugins.

* Refactoring and stylystic fixes of RecordEngine class (and one
  dependency).
* Refactoring and stylystic fixes of DataThread class and all
  appropriate dependent classes.

* Added possibility to select and generate the plugins of appropriate
  available types (Processor, RecordEngine, DataThread, FileSource).
  Now it's only generates appropriate lib files and selects some types
  in processor. However, we should generate different processor files
  for each plugin type later.
* Added possibility to select processor type;
* Some refactoring of existing code and minor fixes;
* Still needs some refactoring of newer code with some improvements.

* Refactoring applied mostly because we need to satisfy the new state
  of GenericProcessor after refactoring;
* Also there were a lot of stylystic fixes applied, some minor
  improvements using C++11.

* Appropriate dependencies also have been changed.

* Now the plugin will be displayed with friendly name in the GUI;
* Hided some future functionality which is WIP now in
  jucer_ProjectType.h file.

* Basic implemntation of Open Ephys Plugin Generator.
  Now it generates empty processor & editor. To compile plugin with
  current plugin build systems we just need to copy "Source" folder
  of our plugin into plugin-GUI/Source/Plugins/ and give it some
  valuable name.
* ExampleProcessor, ExampleEditor classes refactoring and stylystic
  fixes.

* All modules are replaced with the JUCE 4.2.1 ones;
* Introjucer was replaced by Projucer;
* Also some appropriate needed fixes for Makefile.plugins;
* Removed -fvisibility=hidden flag for Linux building.

* Updated images for collapse/show button;
* Updated animations;
* Some other small UI improvements;
* Added possibility to collapse element by clicking "ESC" key
  either on the component itself or on the TextEditor.

* Created SlicerChannelSelectorComponent class which holds inside
  all ChannelSelector's parser related components and which
  takes responsibility for parsing selected range, etc.
* Added possibility to collapse parser related components.
* Added animations.
* UI improvements.
* Minor bugs fixes.

On OS X, the default directory for files explicitly saved/loaded by the user is now ~/Documents/open-ephys.  Added CoreServices::getDefaultUserSaveDirectory(), which returns ~/Documents/open-ephys on OS X and the current working directory on other platforms.

On OS X, the default data directory is now ~/Documents/open-ephys, which is created if it doesn't exist

this should reduce the impact of the remaining 1px plot issue until we
track it down

non plugin specific class defs should not go into the plugin specific namespace
