Add `ag-dired` and `ag-dired-project`.

Add -regexp flavours
Merge pull request #32 from Fuco1/ag-find-regexp

Add `ag-dired` and `ag-dired-project`.
Silencing some byte-compiler warnings.
Use -I instead of -d '\\n'

Thanks grep information, but Mac OSX's xargs doesn't have -d too...
However, I found the equivalent of -d '\n', -I exists ether GNU and UNIX.
It works fine without abnormally exits (in case, caused by blank space file name).
Merge pull request #35 from ShingoFukuyama/patch-1

Use -I instead of -d '\\n'
Version bump following the merge of #35.
Improving installation instructions and mentioning supported platforms.
Allow the arguments to ag itself to be overriden, if a prefix argument
is used.

Fixes #36.
Documenting overriding ag flags.
Mark ag-project-at-point as obsolete.
Clarify in docstring that we always return a string.
Changing ag-project-regexp to default to an escaped regexp of the symbol
at point.

This makes `ag-regexp-project-at-point` at point redundant. The other
FOO-at-point commands were removed (without breaking compatibility)
several versions ago. `ag-regexp-project-at-point` was also
inconsistently named.
Updating changelog for 0.40.
Merge branch 'master' of github.com:Wilfred/ag.el
Define vc-svn-root for older Emacsen. See #37.
Fixing a byte-compiler warning.

You're not supposed to use replace-string from lisp code.
Use a consistent buffer naming convention.
