Requests regarding GLOB support

Two straightforward requests:

• Autodetect file changes. I think Notepad++ runs the check when the window becomes active again, but maybe it can be done with watchdog or something.
• Rebuild the QML code model on changes. At the very least, rebuild the QML code model on Run CMake.

Rewritten as the problems I am trying to solve:

• Adding QML (and CPP?) files manually to the system requires running CMake manually to detect the new files
• Even after detecting the new files, the Editor/code complete/linter? doesn't recognize them until you reset the code model
