Quick open improvements
- Allow opening a file at a specifc line:col. This will happen if you add a ':' at the end and specify line and column. For example:
"kaapp.cpp:201:18"
will open a file the selected file in tree at line 201 and column 18 (if they exist).
- On clearing filter text, try to restore the sorting i.e., bring opened documents at the top again.
