Relative paths for options

[jonnolen]

The paths on the command line should be relative to where the command is run, e.g. the my_project folder, that way you can use the command line autocomplete. That means "-x" argument would change to:

-x ios/my_proj.xcodeproj

At the moment, my_proj.xcodeproj doesn't autocomplete which means you have to autocomplete on ios/my_proj.xcodeproj then delete the "ios/" part.

i think the easiest way to do this is to get rid of the -p option altogether and have the user pass in the full relative path to the xcodeproject. that way the user gets auto complete. we'll dirname the file to get the source path and then append the relative path for generated source to that to get what I need.
