Legacy Parts

This is a new global sub-category implement meant to clean up ParanoidAndroid's settings menus.

Since AOSPA-legacy uses both CyanogenMod and ParanoidAndroid's coding, things were meshed together incoherently. Legacy Parts will now house categories/features not present in the official ParanoidAndroid upstream however, needed for non-Nexus/legacy devices to function efficiently.

Great Thanks to @TheMrcool212 for allowing me to use AOSPAL's remix-settings pagertabstrip implement for Legacy Parts. Also for helping me with a great deal of resource file migration and classes.
