Compatible with Natural Language Dates

[ribber]

In the front-matter, there is a conflict with the Natural Language Dates plugin. When using the "@" symbol to select a time, the Natural Language Dates plugin is not providing the expected prompt. For selecting time, Natural Language Dates is more meaningful. An option to config ignore character will be userfull

I've changed it so that the completr suggestion popup is registered at a later stage, meaning the NL dates plugin popup will be triggered first and if it has any suggestions, block the completr popup. This should fix your issue.

Thank you very much
