Yeah, it seemed like only I like using the dollar-sign, so we're phasing that out.  The documented policy is in https://github.com/mozilla-b2g/gaia-email-libs-and-more/blob/master/CONTRIBUTING.md and is "Module variable names: consistent with variable naming: var moduleName = require('module_name');"  When we discussed that we decided there was no name to do a giant refactor and that we'd just adopt the new policy incrementally as we add/change code/etc.

We might want to rev that more.  I went with ASCP because that's what we use elsewhere in the codebase and activesyncCodepages.FolderHierarchy.Tags gets a little unwieldy.

If you have an opinion, I think we're very open to better policies/ones that provide an example for this case/other.
