Started adding new *verify* command for scss-lint
Moved the code for running the scss-lint command into its own function.
Removed commented out code
Verify the existence of the main sass file; using the  function also gives warnings regarding main.scss listing in the bower.json. Return early as the task should not run if main.scss is not correctly defined.
Add JSHint minimum config defined by the specification

Update the exclusion definition for scss-lint.  It uses a slightly different way of specifying exclusions to jshint and must be a comma separated list of file globs.
Added function to get the list of paths that exist in the .gitignore file for a project

Build the list of exclusions for scss linter from the .gitignore file.  Unfortunately it's not as straight forward as it is for jshint, instead we need to read the .gitignore file and add wildcard identifiers to any directories listed in the .gitignore file
Run the tasks using  which now correctly aggregates the errors rather than failing immediately.  Some mild duplicate code removal

Return with a useful error code
Use globalstrict:true directive for JSHint to prevent complaints about the positioning of the use strict directive.
Add some structure to the task definition by using an object, this allows meta data to be added to a task (such as its name) which can be used in the output (such as a heading for a section of output).
Update comments to reflect code
Made the verify command watchable
Starting to add JSHint to install - need to fix some stuff with command-line.js to remove duplicate process spawn logic
Make whitespace consistent & remove console debugging
Naming consistency & correct use of the output object
Updated README with verify command information
Clearer wording
Typo
Update SCSS linting config with the current one from ft-origami spec.
Added mechanism to transform the output of a tool, slightly hacky, but is relatively flexible so we can at least try and get some consistency between different tools. This also adds an error count to the scss-lint output.  I had to change the childProcess spawn method in command-line as there was a weird bug with scss-lint when using spawn, slightly annoying to try and debug and changing the method to exec fixed the issue
Merge pull request #31 from samgiles/verify-ra

Adds `verify` command to Origami build tools, closes #28.
