* new command (buffer-mode) tells what mode current buffer is running
* new command (camelscore-word-at-point), bound to: M-`
* change keymapping of fold-all-at-level to C-c C-'
* use enh-ruby-mode more frequently (now rake files!), and run progmodes-hook
* minor: move location of (ap-haml-reindent-region-by)

sh:

* alias "mlt" to tail mongo log
* don't load ~/.bash_ext_.* files which match .swp!
