New plugin: Citations (with Zotero)

Hi,

my cloud solution limits me in file lengths. Unfortunately, I decided to use the {{title}} handlebar in the literature note title template and some papers have really long titles, so I get syncing errors I need to resolve manually. For the current errors, I am pretty sure, that I’ll have to do that, but I’d like to have a more failsafe solution for the future by shorten the tile. I found that I could use helpers to do use the JS substring function but as far as I understood the plugin does not allow writing own helpers.
Any ideas how to get, let’s say, the first 100 characters of the title only?
