Major rewrite: less repetition (#101)
* first step of rewriting: at least it compiles™ * fix tabs/spaces * fix dabort on load * fix preview crash * sorting isnt done outside of loading * step one of making remake_file useless * camera/qr code cleanup * fix dabort when folder is empty, and bring back preview optimization * fix button for switching modes and show mode when folder is empty * fix scanning qrs * no more splash discrimination * add debug helpers * fix theme installing turns out that wasnt such a good idea * fix battery icon * mistake * themeplaza compatibility * make use of load_data * don't drink and copy-paste, kids * fix user-agent * remove useless * cleanup includes * not even used * add splash buttons * upgrade buttons drawing * fix controls while preview is up * improve positions
