[Feature Request] Generic output directories

[Adrianilloo]

In relation to #70.

I still think that the configurable output directory should get aliases to designated paths (e.g. %bp_source_directory% that already works within pre/post build options). Ideally, there should be a choicelist to the right of the path search button (...), that contains at least the following options:

• Compiler directory
• Source directory

The path display field would get updated with the mapped alias when selecting each option, and of course, if user choses a path from the search dialog instead, it would override the current field value as well.
