_HasProxy : remove the `toString()` override as it can lead to circular reference errors

while it was sometimes convenient, there were too many side-effects /
dangers in doing this for all proxies.
release version 0.1.2+10.28.2013
0.1.3-dev+10.28.2013
Merge branch 'master' into pr/16
fix keyboard_handler

-renamed `id` -> `path` to be consistent w/ other loaded modules (mode,
theme)
- bind ctor takes one of the BINDINGS and the default ctor takes any
ace/keyboard/whatever path, to support user-defined keyboards
back out accidental _noop from last commit
KeyboardHandler : rename the named factory `bind` -> `named` to be consistent with Theme

Also, have it forward to the unnamed ctor and clean up the docs a bit.
