Code cleanup

[marioortizmanero]

There are many parts of the code that could do with a bit of cleaning up. I would very much appreciate any help on this, I can help out by reviewing any changes:

• The script includes multiple ways of reading properties:

  1. With a while read in getNicknameFromProp
  2. With a good ol' grep pipe everywhere else

  The first actually seems more robust, but the second is more "bash"-y. I don't really care, anyway. The point is that they should be consistent.

• getNickname is quite messy. The if statements could surely be simplified in some way. Or it should be commented internally, at least.

• Overall, many commands are incredibly large and complicated. We could:

  • Split each pipe into a different line with \ so that it's more readable
  • Try to simplify them

• Put all the simple getter functions at the beginning of the file

If anyone else thinks of other improvements, please leave them as a comment here!
