OpenCobolIDE 4.7.3

Improvements:

- add a checkbox in the status bar to quickly switch between fixed and free format
- improve saving and restoring window state (hidden dock widgets will stay hidden).
- allow to see pyqode debug log messages
- improve logging system to easily make the distinction between the current log content and content of other instances.
- don't include full compiler path in default configuration (already set in PATH)
- update to latest qcrash:
    - split report into general and application log
    - GitHubBackend: upload log file as a gist
    - add option to save login only.
- update to latest pyqode:
    - many improvements to the cobol code folding
    - name parser works with incomplete sources (copybooks or programs which have DIVISIONS in copybooks)
    - add zoom menu to the editor context menu
    - add ability to close tabs on the left/right of the current tab.
    - fix cursor not visible under margins
    - and many other bug fixes
- include all available pygments lexer in the frozen build on Windows and OSX (you will have basic syntax highlighting
  for file that are not cobol sources, e.g. bash, foxpro, ...).
- simplify new file templates + use free format setting to choose the correct template.

Fixed bugs:

- fix compiler output not parsed correctly if ';' in error message
- prevent overriding RunEnv['PATH'] by CompilerEnv['PATH']
- fix linter not working if no compiler full path specified (will now use PATH to find the full compiler path).
- fix clear logs not working on Windows
- fix PermissionError when determining the available icon themes
- fix spelling error GnuCobol -> GnuCOBOL in about dialog.
- fix external terminal not working anymore on GNU/Linux.
- fix generic editor's backend not working in frozen mode
- fix default icon theme not correctly detected on Plasma 5.6 (maybe on other linux desktops too).
