Brings flexo into client api.
-This is because all current plugins are compatible with the newest flexo api, so backwards compat may not be as necessary as I believed, and it causes a lot of extra work needed to be done when updating..
Flexo
-Adds pauseMS
-Adds typeMessage
-Adds holdKey
-Adds holdKeyIndefinitely
-Cleans up a lot of unused code.
Flexo hosting on the maven repo will cease after next bootstrap update.
