"ZOBS" (obsolete) tag and adds a "TDRC" tag at the end of the
list of tags using the first 4 characters of the "TYER" tag.
Since we write both the "TDRC" and "TYER" tags, the "TDRC" tag
will always be encountered first in the list. We want use it
since the converted "TYER" tag may have been truncated.
Refer to bugzilla for discussion, but, to summarize, this removes any writing of ID3V1 tags. ID3V1 tags will still be imported, but they will be written as ID3V2 tags.
Also some minor refactoring.
This feature works with mp3 right now - may work on other formats, but that will be a seperate commit.
It is not enabled so most of the changes won't even be compiled, and those that do won't be run.
To enable it uncommment the EXPERIMENTAL_ODFFMPEG def in Experimental.h
* /ExtendedImport/OverrideExtendedImportByOpenFileDialogChoice preference enables the override (backward-compatibel behaviour), and it is now false by default
* File names (and mime types) and patterns are Lower()'ed before being fed to wxMatchWild(), now matching should be case-insensitive
* Now empty rule elements (empty list of extensions, empty list of mime types) will match anything (just as if they had one "*" element)
* "Extended Import" preferences tab is now next to "Import/Export" tab
* Preferences now use Grid class (the one used in Tag editor) instead of default wxGrid. Tabbing now works correctly.
* First attempt to add Drag'n'Drop re-ordering for Rule table. Seems to be working.
* Cleaned up a couple of cruft code comments.
* Separate buttons (with hotkeys) for moving rules and filters up and down (ctrl+up/down still works)
* Moved some code into helper funcions (can be called from both button and keyboard event handlers)
* Grid is now configured in PopulateOrExchange (the same way it is in Tags.cpp)
* Keep selection while moving table rows and list items
* Detect trailing/leading spaces in rule condition and offer to trim them
