To exclude a file from a build for a given target, now the user have to go to the Project navigator, click on the file
choose Properties and then choose "Exclude from build". This work flow is cumbersome especially when there are a number
of different binary targets and the number of files is large. It would be very nice to have the "Exclude from build" for
the current build/target in the Project navigator's context menu, something like Eclipse CDT has. Also it would be a
very nice enhancement to be able to do "Exclude from build" for more than one file at once.
