Inital release of Telegram Desktop cleaner

[Tobias-B-Besemer]

Should bring big benefits! E.g. in my case the folder "cache" have more then 160MB and more then 15.500 files !!! Should also be a big privacy benefit! The file names in "cache" are encrypted and have always random 12 letters and no extension and should also just partial files... but for a person with forensic knowledge it shouldn't be to difficult (also because code to Tg Desktop is OSS) to restore e.g. all the pictures which was shown to a user... As Tg is now a really famous messaging app and it seems this data doesn't get deleted by other solutions such as WinApp2.ini, I would suggest to move this cleaner soon (for BB3.2/4.0?) into the release (stable)... Coded this cleaner ASAP in the last minutes... so haven't really tested him, yet! Hope maybe a other person interested in the BB project will do it soon...
