Bump minor version - will probably change API. Target Guard >= 2.0 and Slim >= 2.0.  Add :input and :output as aliases to :input_root and :output_root.
Respect :input (:input_root) configuration on run_all.  From stevehodgkiss/guard-slim commit by aiwilliams.
Prevent Guard from firing Guard-Slim when there is a rendering error.
We want the error reported, but it's a pain when Guard fires Slim because of malformed markup - it should keep running.
Upgrade Guard-Slim to use the Guard 2.x API. Add a CHANGELOG.md.  Currently broken (wrong number of arguments (1 for 0)) attempting to create (new) Guard::Slim.new(options) -- ???
Fully specify UI class. Attempt to get Guard properly loaded...
Update Gemsepc, Add MIT license, add some logging and return true from all the guard calls (start, stop, reload, run_all, etc..)
Support Slim plugins via slim: { plugins: 'slim/plugin_name'} option. Verbose option via verbose: true/false to show more information about what guard-slim is doing. Display a stack trace if we rescue a StandardError.
Version bump. CHANGELOG.md update.
