Consider renaming to active_record_annotate

[westonganger]

Something to note its pretty awkward to use both underscore and dash in the gem name. Usually that denotes a plugin for a gem and even then I find it bothersome as ruby prefers underscores in general.

gem "active_record-annotate"

I recommend renaming to:

gem "active_record_annotate"

I checked rubygems and even github completely and this new name is not taken.

I simply want the visibility & adoption of this project to be as high as possible because its "so much more Rails" than the more popular annotate project.
