#245 Build Options by Project pane folder

[Matthew Orlando]

It would be nice to be able to choose build options for
all source files in a given Project folder.

Example: I am working on a project which uses a lot of
inline methods. In order to facilitate better OOP
practices (eg. data hiding and encapsulation), I
implement the inlines in seperate source files. Because
they are directly included at the end of the headers,
they shouldn't be compiled. I have my project separated
into headers, sources, and inlines, and it is kind of
annoying that I have to tell it to ignore each inline file.
