- Tags tab now shows common tags if multiple files selected.
- Apple Lossless > AIFF copies tags

Note: previous "Load track Names from file" was moved from the Edit menu to the File Menu.

- Added ability to parse an info text file for track names. From the "Track Name Input" window, select "Load Names From File" from the edit menu and choose a text file. xACT will attempt to parse track names in the file. It looks for lines that start with some variation of a track number: 01 or  or (01) or [01.] etc. Note: this function is incomplete, very basic, and won't work for all cases.
