Simplified tag editor for ogg & mp3

[ezekiel000]

The tag editor could be improved by simplifying it by default with and advanced editing option that uses the current editor.

This "wish" will be solved in 3 steps:

Step 1:
Add Next/Prev functionality in current tag editor

Step 2:
Implement support for rename without open tag editor and create a way to enable it.

Setp 3:
Add keybing support for Step2.

Any suggestions?

Step 1: Was implemented (not by me)

First patch:
Navigate editing playlist tag if *just one* track was selected.

Committed, thanks. As discussed in IRC, it would be good if you can add some documentation regarding the "selected" argument.

Changed name to "current_position" and propertly documented with r3531. The remaining suggestions can be tracked in #570978.
