Cache application.encoding within HTML class to avoid unnecessary calls to Config::get();

Calling the "Config::get('application.encoding')" is expensive and within a large form (using the form builder) having it requested multiple times can result in a significant performance drag.

Caching this value reduced calls to Config:get within our project from 1200+ to 125. All core tests appear to pass with this change in place.
Refactor changes into single get_encoding() method within the HTML Class (in order to remove duplication of logic). All tests continue to pass.
Update to conform better with laravels coding style.
Rename static::get_encoding() method to static::encoding() to fit better with style.
Reformatted return

Changed the return of the method in line with suggestions from @JoostK.
Changed DB config hosts to IP addresses
