Release 2.2.3 - Fix for MaterialTitleItem and Support Library version support.

Fixed #70 in this release and addressed the issues regarding support library conflicts. I apologise for not updating to support the new support libraries (that's a mouthful) sooner since I have been abroad and away from my computer for quite some time.

You can now use a different version of the library depending on which version of the support library you use: https://jitpack.io/#daniel-stoneuk/material-about-library/

For example, to use the latest version of the support library you should use:

compile 'com.github.daniel-stoneuk:material-about-library:2.2.3-support26.1.0'
