Speed build time up by 6 using multiple jobs

Adding aggresive build mode that spawns num_core+1 jobs. This speeds up
build time by 6. On my 8 core machine I'm down from 6m:16s to 1m:34s.
Fixed typo
Do not set number of jobs if already specified
Adding CodeLite and KDE files to .gitignore
Adding CodeLite hidden folder to .gitignore
Adding new OpenGL4 driver

Still empty though.
