Added test-build utility
Made executeable
Fixed variable name
Fixed usage call
Fixed if-then
Formatted output
Added cyan as color
Output should be cyan and in STDERR, so it doesnt mess things up
Added some output
Use the basename here, not the full name
Changed to pass start revision directly

I would like to pass the rev directly: ./prog master

So, we must check if the passed argument is a real revision. This patch
refactors the source into this approach.
Aligned the usage output
Added support for executing `fg` on success or `git-bisect` on failure
Removed outdated argument from help text
Removed old argument from argument parsing
We should use the bash shebang here
Were writing bash here, so lets use the bash features
