Updated vim_emu

Updates for vim_emu.

New features:

* New ChangeKeys in addition to Esc/C-[ (e.g. simultaneous jk toggles Normal-Insert Mode.)
* Fixed visual line action starting with up move.
* German Keyboard Support.
* Removed all repeats (such 4w for 4words), because it affects on the OS performance, even if it is not checked. (codes are commented out, but in setting files. it can now be used for visual/yank/cut/change modes, too, if enabled.)
* Removed Visual Block Mode. Same as repeats.
* New Options:
  * Recording Macro: By using [MadRuby](http://www.wingsforpigs.com/MadRuby/MadRuby.html), vim_emu can record key inputs and replay it.
  * Disable all non-assigned keys in other than Insert Mode.
  * Ctrl-[ to Escape for non-vim_emu apps.
  * Ctrl-[ to Escape in Noraml Mode.
  * Reset vim_emu at non-vim_emu apps.
  * Reset vim_emu at left click in any case.
  * Reset vim_emu at Cmd-Tab in any case.
