Remove channel/private group name restrictions. I added this in myself as a side effect of their routing changes. It is NOT supported by RocketChat. We slugify the name and use it as the id. The raw name is saved as a separate displayName field. Only restriction is that we can't name a channel/group if the slugified value already exists. e.g. pg1.1 and pg1 1 would have the same slug value of pg1-1
They added system backend methods that I requested for creating channels etc.
