Fixed bug with not opening the editor when clicking a file from the file browser. Implemented watching the file on disk.
* MainWindow: Simplified opening file request calls.
* FileEditor: Added new slot that closes tabs without and index and made FileEditorTabs connect to it.
* FileEditorTab: Added QFileSystemWatcher and fixed bug with setting modified status on m_modified. Implemented message boxes for the cases that a file has been removed, renamed und modified from outside.
