Removed local org related values from custom

Re-added (thought these were already in?)

* coffee mode
* dash mode
* multiple-cursors

Added:

* csv mode
* dart mode
* multi-web-mode <- this is great.

Re-implemented some defuns in handy-functions to use
composition. (things based on the s sting library, which operate on
thing at point or region, now re-use the same replace engine, a defun
called operate-on-point-or-region) - Cleaned up some doc strings, etc.

Markdown.css added for previewing purposes.
