Adding optional color support.
Fixing a weird extra space in a spec name.
Logsaber#create options are now a hash, instead of positional.
Moved code into Log class, so that Logsaber can be a namespace without getting so cluttered.
Extracted formatting logic out into Saber class.

- Changed Log's default_options into a local,
  so we could create new Saber instances each time.
- Created the Log#view,viewable?,analyze methods.
  They clean up the extract_details block pretty well.
Adding Travis-CI configuration.
Adding links to Edge/Release Readmes and the CodeClimate badge.
Use Uspec instead of Rspec in CI.
