Add case Sensitive tags for Auto renaming [DONE]

[LEECH666]

Well its just a matter of taste but I like to have UPERCASE checksums.

So using UPERCASE tag-strings in the Filenaming Pattern would be very nice.

Example

%crc32 - [dd010b7b]
%CRC32 - [DD010B7B]

Not very important though :/

I have plans to add something that does the same, on todo but not super high prio atm.
