Work with subfolder installs

This ties into your item about working with different permalink structures (listed in the ReadMe) but currently no content displays if WordPress is installed in a subdirectory.

For example, on my local machine I have a bunch of WordPress installations all within a single parent directory accessed something like:

127.0.0.1/core/
127.0.0.1/dev/

Picard didn't work to display post/ page content when installed into one of those, but it does work when installed in the root install at

127.0.0.1

Reproduce the issue with WordPress installed at a subfolder such as /core/ or /dev/, then compare it with a root installation at 127.0.0.1. Trace why Picard displays no post or page content in the subfolder case. Done means post and page content renders correctly for both root and subfolder installs.
