Autoload Terminator Capture too
Add note about new core and its requirements to README
TerminatorCore requires xdotool.
Use Terminator core & capture if terminator in PATH
This overrides the default setting of Konsole core and capture on Linux,
if the "terminator" binary is found in PATH.
Implementation for Terminator core.
Couple of gotchas:
* only works if the active window at the start of any invocation
is a terminator window, and all commands operate on that, and
* requires the "xdotool" utility to be in the path.
Unit tests for Terminator core
Basic structure aped from Konsole core tests.
Capture class for Terminator
Just and empty implementation for now.
If growlnotify not available, output with puts.
This allows using watchr to run the tests on e.g. Linux.
Only run mac-related tests if platform is darwin.
When on linux, add ruby-dbus as dependency
