Added a flag within the base theme to turn version control checks completely off or on.
Added the base theme version control status check flag to the template bash profile. This will allow for easy changing of the flag's value without needing to understand the base theme file.
Fixed typo in comments.
Added SCM_CHECK flag documentation.
Fixed script execution to always use the frontmost window, instead of window 1.

If you had multiple terminal windows open, there was a chance that the command was sent to another window (the one with index 1). Using index 0 will execute it in the currently visible window.
Added ability to enter a few characters at the prompt and then search backwards/forwards through history with up and down arrows
Moved arrow-keys-search-history from lib to available plugins
Merge branch 'feature/upstream_update' into develop
