ui: Revised project setup to customer feedback

* Support environment variables in compilation database path
* Moved advanced option (compiler flags & exclude paths) to separate dialog
* Allow environment variables that contain multiple paths
* Renamed 'Project Name' to 'Coati Project Name'
* Renamed 'Project File Location' to 'Coati Project Location'
* Renamed 'Project Paths' to 'Indexed Paths'
* Make all paths chosen by path picker relative to the project location
* Disabled name and location changing in project editing and removed project moving
* Added sub-titles to project setup dialogs
* Warn user when no Indexed Header Paths were set
* Deprecated lazy include search: It's only useable and visible to projects holding the key
* Split default file extensions for C++ and C
