New theme - Crunch

themes/crunch.zsh-theme

+# CRUNCH - created from Steve Eley's cat waxing.
+# Initially hacked from the Dallas theme. Thanks, Dallas Reedy.
+#
+# This theme assumes you do most of your oh-my-zsh'ed "colorful" work at a single machine, 
+# and eschews the standard space-consuming user and hostname info.  Instead, only the 
+# things that vary in my own workflow are shown:
+#
+# * The time (not the date)
+# * The RVM version and gemset (omitting the 'ruby' name if it's MRI)
+# * The current directory
+# * The Git branch and its 'dirty' state
+# 
+# Colors are at the top so you can mess with those separately if you like.
+# For the most part I stuck with Dallas's.
