Allow Revisr to handle different WordPress structures

[mattgrshaw]

Quite a few people have requested using non-standard WordPress structures: https://wordpress.org/support/topic/recommended-wordpress-structure

This would mainly be helpful for people who are already using Git in their workflow and would be using Revisr to either supplement or replace their existing workflow.

Possible solutions:

• chdir() to ABSPATH before running git rev-parse --show-toplevel in Revisr_Git::current_dir()

Also likely related is issue #22

This has been partially supported with the addition of the REVISR_GIT_DIR constant. This can be used like so:

define( 'REVISR_GIT_DIR', dirname( __FILE__ ) );

Closing, only #22 is pending regarding this issue.
