Change success logic in Options controller to treat the save as successful if any individual option update persisted (use OR instead of AND), preventing a single-failure from marking the whole operation as failed. Fix Options_model to return TRUE after inserting a new option so inserts are reported as successful. Add a saveFailed flash message display in the email options view so users see explicit failure alerts when appropriate.
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.
