Revise list of undesired theme names

The term “Creative” is no longer part of the list of undesired theme
names.
Adapt TitleCheck for WordPress 4.1

Themes can add title tag support starting with WordPress 4.1. When
title tag support is added, no HTML title tags or calls to wp_title()
will be in the theme, so the checks in TitleCheck should be skipped in
that case.
Remove ThemeCustomizeCheck

This check is not needed for the WP.com Review Type and it it
references deprecated functions. See #214.
Remove HardcodedLinksCheck

This check is not needed for the WP.com Review Type, as this will be
caught during the review. See #214.
Update ThemePostPaginationCheck

Update ThemePostPaginationCheck to work with the (get_)the_pagination()
functions added in 4.1, add Unit Tests and add to the WP.com Theme
Review Type.
Remove spurious parentheses from VIPRestrictedCommands[Check|Test]
Move check for WP_User_Query to a class and file of its own

Moving it out of VIPRestrictedCommandsCheck is a preparatory step
for using PHP-Parser for checks, as all the other checks in
VIPRestrictedCommandsCheck are for function calls, not classes.
Add a test for VIPRestrictedClassesCheck
