Read per-podcast settings from file
  The previous setup of hard-coding for each podcast how it is to be titled and how it is to be placed into the archive has been replaced by a settings file "pod-data.txt".  That settings file now contains what was previously specified by multiple arrays, and a bunch of if-then-constructs.  Thus the data has been abstracted from the code.  Due to that the amount of code has been reduced.  It should now also be significantly more easy to add new podcasts.  The "pod-data.txt" file consists of a bunch of entries separated by a newline.  Each entry consists of a key (field "podcast" in the OSF header), and a bunch of sub-elements, that is values.  The values are the following:
  - name
  - long_name
  - webpage
  - default pattern for episode titles
  - pattern for archive name
  - html of the logo
