uid vs uuid in Show

[hairmare]

nowplaypadgen uses uid:

nowplaypadgen/nowplaypadgen/show.py

Line 57 in 5e37ce0

self.uid = uid #: The show's global unique identifier (UUID)

while nowplaying uses uuid:

https://github.com/radiorabe/nowplaying/blob/6c4ce335c40a17e6d07d82538d8e862772a641c7/nowplaying/show/show.py#L27-L28

Since uuid is the more specific name, nowplaypadgen will use it as well.

This affects the Track class as well.
