- Restructured the files into appropriate directories:
  -> GUI: contains "headers" and "source"
  -> Plugin: More to this later, need to create subdirectories for headers and
             source files. And change the VC directories to include the changed
             directories.
- Added the functionality to erase configured buttons in Keyboard tab by either
Right-Clicking on the animCtrl (icon of ps button) or txtCtrl (the configured key
associated to the ps button).
