[Options] Greates OptionsLib library, sets default theme and others

This commit does a couple of things

- Creates OptionsLib which stores the 'Options' within the CI config system prefixed with "options_"
- Loads the OptionsLib automatically
- Adds function to OptionsLib for selecting the active stylesheet.
- Adds function to get an option_value that isn't automatically loaded.
