Fix issue #46

This is a temporary fix for issue #46 until the next Cobra release.
Ultimately, we want to be using the runAndCaptureOutput method of
the Process extension.
Merge branch 'master' into cleanup

Conflicts:
	CobraBinding/CobraLanguageBinding.cobra
use runAndCaptureOutput Process extension method instead of closure
Update minimum required version of Cobra
Use correct column numbers with binding errors
Ignore one-line regions and don't throw when can't find node

This also includes some temporary debugging code.
Remove debug print statements
Add new method: resolveOffsetToWord
Fix unit test on Windows
Add tooltips for keywords

Only a handful of keywords will have their grammar displayed but all
keywords should include an English description.  Some issues remain
such as how do we show the correct tooltips for method overloads when
hovering the mouse and how do we show alternate grammar for various
keywords in different contexts?  A smarter approach to parsing might
help in these scenarios.
