elexis 85a622b13a Implement IGUIObject settings as a template class and IGUIObject::AddSetting as a template function.
This means the type information is available for all methods operating
with the setting type, which is easier for the authors, allows for
compile-time checks and optimizations.
Remove the enum that was used to indirectly obtain the setting type at
runtime.
Revises SGUISetting and enum from e326ebae46 (5122b0f906),
std::function from 82f1d2718b.

Differential Revision: https://code.wildfiregames.com/D2145
Tested on: gcc, clang, VS2015, Jenkins

This was SVN commit r22604.
