Michael Niedermayer b3c3996212 avcodec: rename prores encoders 
Using the first names of authors sounds somewhat unprofessional
and might be considered offensive which is not intended.
The new names use the initials of the authors due to simplicity
and the possibility to apply it consistently without the need
to find political correct names for each future case where
alternative codecs might exist. Also its shorter ...

If someone has a better idea, like maybe 2 random letters
and people prefer it then iam happy to switch to that ...
