ace-jump, visual to primary

In response to [this issue](https://github.com/patbl/colemak-evil/issues/20), added the patch as 4be605f.  Not sure if it actually affects you.

Added ace-jump keys, replacing find char/backward.  These allow you to jump to char on entire screen, demo [here](http://dl.dropbox.com/u/3254819/AceJumpModeDemo/AceJumpDemo.htm).  Requires the ace-jump-mode package.

The version assigned to "f/F" (formally "find char") lists only nearby characters that can be jumped to in one step.  "b/B" (formally "Repeat/Reverse find char"??) or "C-f" lists all visible characters.  These can be changed as needed.

Some of the proposed commits change the license/warranty statements.  Just to clarify: I am not a lawyer, and this is not legal advice.
