Image filename and movie filename fields don't allow the use of %$ conversion specifier

[xj25vm]

Motion allows the use of %$ conversion specifier as the camera name - including in picture_filename, snapshot_filename and movie_filename. However, Motioneye doesn't allow this - presumably as it thinks it will be passed to the OS as is. Would it be possible to change the code so that Motioneye recognises %$ as a valid character sequence in paths please? I noticed that Motioneye already allows the use of %$ in the following fields: , on_event_start, one_event_end, on_movie_end, on_picture_save
