Optional HSTS support and bugfixes

Mostly a few bug fixes and optional support for HSTS :)

Enforce home page SSL redirect

Apparently when preparing the future admin screen, by adding a new settings class, the SSL force constants wouldnt be set up all the time. Also, some minor issues with missing action hooks prevented the plugin to fire when called on the home page vs. on any other page.

All of this should be fixed now with the current release ;)

Cache support orgy

Added cache buffer support for:

• WP Fastest Cache
• Hummingbird Performance
• our own future simple cache / output buffer system (which should come around in 2.0)

Support for Simple Cache plugin

Added support for Simple Cache plugin.
Started initial preparations for adding a functional admin screen, including options. Also see Changelog in the readme.txt file.

1.3.3: Minor fixes

Minor fixes and improvements. Preparation for the optional admin interface, coming in release v1.4 or 1.5.

First official stable release

• Added support for Hyper Cache (hooks into the cache_buffer filter hook, which fires right before the buffer is processed)
• Changed the call of the DOM-aware replace filter to be only enabled by constant (_UI_SSL_ENFORCER_DOM_PARSER), as it sometimes causes issues with inline script snippets
