[enhancement/feature] registerPartials [async/sync] and renaming files to underscore.

[iwaduarte]

In relation to registerPartials being async #68, #159, #123.
Wouldn't you think it should be sync ? Considering we move our structure application towards partials and sub-partials and also because it is only executed once. I believe in most cases does not add any significant overhead to the efficiency of the platform overall.

The walkSync is a good approach as suggested.

In relation to renaming the partials.
I have partials named [partial - specific.hbs] and gets renamed to [partial _ specific] when registering. This is kind of annoying (hífen to underscore) since if we want to use the uri paths (/user-add) directly we would face this challenge of having to rename it every time in the application instead of locate the partial right away.

Hi, I am here to help out with the maintenance of this module and working through the issues and PRs. I agree on both points of your issues. The first part I just pushed a fix for on master to release soon. To your second point, I agree that it is too opinionated. I will add an option to the registration in order to specify how to translate filenames to partial names (and thus even disable it as well), which should address your use-case.
