Refactor: python: Improve resourcerecover.py.

• Disable pylint warnings we can't really do anything about.

• Simplify how the pats lists are built.

• Get rid of the max attribute. It is unused.

• Rename most attributes to use a leading underscore, since they are private.

• Rename all methods to be private and follow python naming conventions.

• Use %r instead of repr in format strings.

• Use a list comprehension instead of map(str.strip, lst). You're not really supposed to use map anymore, though I'm not sure why pylint isn't warning on this.

• Get rid of unnecessary elif statements.
