Added vim plugin

Created vim plugin structure under src/main/resources with error
formats and recommended commands.

Added vim-install-plugin and scoped base-directory key to support
installing the plugin files into the appropriate location.
Update README.md

Fixing things that I missed when I updated the file for this feature.
Some tweaking to account for sbt file() method

I noticed the file() method in some documentation or a
presentation and it really helps to clean up the code.
Merge branch 'feature/install' of github.com:dscleaver/sbt-quickfix into feature/install

Conflicts:
	README.md
Updating version for this release

Moved the version to 0.2.0 and added the git revision to the
version string for this release.
Fixing plugin package declarations

I just noticed that all of the package declarations were
org.dscleaver instead of com.dscleaver. Not that it matters,
but I like consistency.
Adding test listener to write test failures

The test listener will attempt to determine the line in your code
that caused an exception. This could be within the test or the
main source files.

Currently tested with Specs and ScalaTest.
Updating ToDo list in README
