Add Code Organization
Rename phpunit.xml to phpunit.xml.dist

PHPUnit supports both and since we're distributing
this package, it's better if we ship a .dist version.

This way if somebody wants to make and edit, they
can add their own phpunit.xml and it will be used,
instead of ours.

The path just changed in core tests framework.
Update WPCOM_Liveblog_Entry's comments
Add Major Design Decisions in HACKING.md
Rename WPCOM_Liveblog_Entry_Query::key_by_get_id()

We're using key in other parts of the code with a
different meaning, so we'd better stay away from it
here.
Update comments for WPCOM_Liveblog_Entry_Query
Rename filter_liveblog_entries to more descriptive

Currently the method only removes entries, which
have been replaced by other entries in the same
set, so we are renaming it to remove_replaced_entries.
