Eclipse Hint: Speed up building by enabling parallel build

[STBESP32]

Hi !

By enabling parallel build you can speed up the build process a lot.

Simply go to:

Project -> Properties -> C/C++ Build -> Behavior tab (important to make sure you select the project)
Check "Enable parallel build"
Leave remaining entrys as they are.

Apply, close and enjoy.

On my Core i7-3720QM i was able to reduce the build time for the "scan" emaple from 7:40min to 2:25min.
