Frameworks: TRLS [1/5]

Initial publish of TRLS frameworks patch. Please no bug reports. I'm only publishing this as a preview. It's still very much a WIP.

PS: remove system dialog hololight themes due to clashing
        with apps that use system dialogs with their own
        resources/text colors, resulting in a white foreground/
        white background (unreadable).

PS: increase readability of notification icon
