v0.2 changelog.
Refactoring: split ome files to core and modules.

Files in core is the foundation of oh-my-emacs, and is highly
recommended. These core files will be loaded by default.

Files in modules are optional, users can load necessary one as he like.
Only enable linum-mode in text-mode and prog-mode.
Add a new ome-experimental module.

This module contains various experimental packages. Load necessary ones
as you like.

Currently, it only contains "sr-speedbar".
Add smooth-scrolling to ome-experimental module.

This package is quite young, so I add it to ome-experimental module.
Disable flymake in elpy, use flycheck like other ome modules.
Store saveplace information to hidden file.
Refactoring: customize el-get package with one function.

This makes code more consistency, also make it possible to write a new
defmacro like "(ome-install el-get-package-name)" which will call
"(ome-package-name-setup)" automatically if it exists, thus makes code
more concise. Convention over configuration, ha.
Fix a load order problem related to evil-leader.
Require inf-ruby before customization.

Inf-ruby does not autoload various variables required by oh-my-emacs
customization, so I have to (require 'inf-ruby) explicitly. However,
I've already made a patch, see
https://github.com/dimitri/el-get/pull/1402.
[#21] Enhance ome-load, allowing load multiple part.
Enable git shallow clone to save time and bandwidth.
Disable single quote pair in geiser-repl-mode.

I've already made a patch for smartparens, see:
https://github.com/Fuco1/smartparens/pull/178
Revert "Disable single quote pair in geiser-repl-mode."

This reverts commit 186fc3402f2145f0d28ea00271dba3d5591163a0.
Patch for smartparens has been merged, see
https://github.com/Fuco1/smartparens/pull/178. So this commit is not
needed any more.
Remove ac-geiser, since el-get merged it.

See https://github.com/dimitri/el-get/pull/1387.
Add hungry-delete to ome-experimental module.
Only defun when executable-find lisp-impl.
Toggle on auto-complete in text-mode and org-mode.
Enable filename completion in text-mode and org-mode.
Todo list cleanup.
