feat(conventional-changelog): adds grunt-conventional-changelog task

this adds brian's awesome grunt task to generate changelogs automatically
through well-formed commit messages.

there's now a new section in the gruntFile.js called 'changelog', which
specifies the options for the task.

for more information about the grunt plugin checkout btford/grunt-conventional-changelog
its readme file also describes where you can find the specification for
well-formed commit messages.

Update CONTRIBUTING.md

Removing the "fork from dev" requirement. Seems like an unnecessary step.
Update controller to fix optionLabel issue.

The optionLabel doesn't show up for multiple dropdowns bound to the same configuration object - only for the last one. This only happens when the DataSource is created using new kendo.data.DataSource. Literal declaration is fine.
