Support for eclim command project_build

[root42]

It would be nice, if there was a function eclim-project-build-current-file, which, if no argument is given, builds the project that the currently visited file belongs to. I tried this on the command line:

  $ eclim project_by_resource -f SomeFile.java
  "SomeProject"
  $ eclim -command project_build -p SomeProject
  "Built project \u0027SomeProject\u0027."

So I guess this should be pretty straight forward to implement.

@fred-o just a tip, if you put a hash and the issue-number into the git-commit message, github will automatically link your commit in the discussion. like:

Added the eclim-project-build function. #60

[fred-o]

Yeah, I always forget that one :)
