Rewrite Complete!

I finished my rewrite!

Here's what's new:

• The script is now way faster.
• You can now pick what gets displayed and where using an array
  at the top of the script. This also allows you to:
  • underline anything
  • print custom info
  • print a custom title
  • add linebreaks
• Mac OS X support and a base that allows us to add other OS later.
• You can now specify split size.
• Fixed issue with 2 line prompts
• Fixed image not displaying in vte based terminals
• Move all config options to the top of the script
• Moved almost everything to a function.
• Removed wmctrl dependency
• Made variable names more consistent
• Added shell substitution for cpu output. This means
  that the cpu output won't include: (tm) (r) "Processor" "CPU"
• Optimized all get* functions
• Use variable substitution where possible as it's faster than sed/awk
• Moved crop and smart_crop to crop_mode
• Removed --size and --padding in favor of --split_size

Here's what I'm currently working on:

• Window support (I'm almost done)
• Option to swap the image and text around
• Imagemagick optimizations
• Cleanup of info array handling
• More info outputs. Now that it's easy to customize what's printed and
  everything is a function we can add optional support for pretty much anything.
  • Resolution
  • GTK themes
  • Terminal Font
  • GPU
  • IP
  • etc

Issues:

• Uptime doesn't work in OS X yet.
• If the customizable info includes a third colon then it breaks.

I'd love to hear your thoughts.

Dynamic Images and Padding

Changelog:

• Added flag to disable bold text --nobold
• Added flag to disable text wrapping --nowrap
• Moved to using only printf instead of a mix of echo/printf
• The script now aligns the cursor to the bottom of the
  terminal instead of using a hardcoded amount of newlines
• Image size and padding is now dynamic, the only difference on the user
  side is that instead of setting a long line of spaces as
  padding, you set your font width. This means that you set the
  var once and the script will just work at any window size.
• You can disable dynamic images and go back to the old
  behaviour with by using the --size or the in config var.
  $img_auto
• Manual padding now takes a count, so --padding 10 will pad
  the text 10 spaces.
• tput is now a dependency because we need (tput cols/lines/cup)
  for the dynamic images and it allows us to support more terminals.
• Color block width can now be changed with the flag --blockwidth.
  It takes a count like --padding so --blockwidth 10 will make
  the color blocks 10 spaces wide.

Let me know if you're having issues.
