Tests for shares and disks tabs

Added some basic tests on shares tab for creating and destroying shares.
Added  tests for Disks tab on showing disk information and conversion to Fahrenheit / Celsius.   I set test environment to load sample disk data like development does to make testing simpler.
Also fixed a broken link in readme to the ruby beautify tool.  All files I edited were run through tool, hopefully shouldn't have whitespace issues like last time.
