• Added simple checkhealth
• Fixed: revins would not disable when leaving Bidi-Mode
• Fixed: sterilizing buffer contents before passing to fribidi

• You can now select your base direction when calling :BidiEnable.
• Error handling in buf_enable_bidi() and buf_disable_bidi() is now corrected.
• Split MX direction into ML and MR

Added buf_get_bidi_mode() which returns the current base direction code (LR, RL, ML, or MR). It's meant to be added to a statusline.

Add :BidiEnable and :BidiDisable. Currently, these only invoke the default base direction.

This dev release adds the function fribid(), which pipes lines through GNU FriBidi.
