CodeLite workspace folders (groups)

[Gaztin]

Didn't notice until today that groups for codelite wasn't working. The change was very small, but I had to update from the manual indenting ( _x(1, ...) ) to pushing/popping. Wrote a test as well. Feedback is much appreciated.

Example:

workspace "groups"
...

group "my/nested/samples"
project "nested_grouped_sample"
...
group ""
project "sample"
...
group "samples"
project "grouped_sample"
...

Result:

Cool, thanks! I appreciate the unit tests and screenshots.
