Summary:
This adds support for flipper logs in Sandy, including some theme adjustments.
Did remove storage and showing of debug messages, as I noticed it tends to crash Flipper after a while since there are so many. Also added a fixed limit of only remembering last 1000
Also converted Toolbar and button with dropdown items to Sandy.
