Add command to print a table with the patched modules

To print the table type: recipy pm

This command uses tabluate. If tabulate isn't installed, an error
message is printed.

Todo:
- add tests for this command
- show warning if the patched modules are empty; this means that
  recipy hasn't been run (the patched modules table is filled every
  time recipy is imported)
