Implements feature: Ability to set Font Color

Implements a feature enabling the user to set the Font Color alongside
the Background Color of the tiles.
Implements feature: Set Tile Transparency

Implements a feature enabling the user to set the transparency of a
tile alongside the Background Color of the tiles. This has been
implemented as a global setting affecting all tiles.
Implements feature: Static Featured Image Overlay

This feature implements two new settings on the “Feature Image
Animation Type“ drop down namely a static overlay of the post title and
blurb over the feature image and the absence of an overlay. The former
is useful if combined with the transparency feature. The latter should
be the default when jQuery is turned off.
Implements feature: peek title

This new feature is designed to work with the “Featured Images”. It
will show an overlay with just the title of the post. Its best suited
to work in conjunction with the Tile Transparency and Slide Up
Animation features.

Important notes:
- This feature requires jQuery to be turned on.
- This feature does not play nice with Responsive Tiles.
- This feature only works with animation type “Slide Up” or with a
“Static Overlay”.
