text editor changes
* out of sync text dosnt automatically popup a menu anymore since it was too easy to click on it without intending to, moved this to an alert button on the header.
* "_" character was acting as a delimiter, but in python its not.
* renamed "File" to "Text" (so as not to confuse with blenders file menu)
* added redraw_alltext function to remove many duplicate loops where every text display is redrawn.
