16/24bit depth column

[Steven]

This is what I had when using a custom tag and Mp3tag to write the value.
Since MB is automatically populating the field on file import, maybe the best outcome would be;
1/:  "Unknown" for any older unscanned files
2/:  Bit Depth for lossless formats
3/:  Leave it blank for lossy formats with the tooltip; "Only lossless formats have fixed bit depth"

Because of the last change i made, i wont be able to do 1
I agree 3 is a good idea, so i will add a tooltip in the main bit-depth column where applicable - not implemented as i am not sure users would think to hover the mouse over the field

Also when <bit depth> is used in virtual tags, rather than saying "Unknown Bit Depth", i will change it to stay blank

fix for rescanning some lossy m4a files incorrectly setting the bit depth to 16

It's fixed. Thanks!

Also if you prefer to see 16 (or whatever) instead for all files with the field blank, use this.

Code

$IsNull(<Bit Depth>,16,<Bit Depth>)

Between the default for lossy now being "blank", and access to the code above (thanks redwing!),  all bases are covered!
