templater: add separate() template function
A pretty common pattern in templates is adding conditional separators
like so:
{node}{if(bookmarks, " {bookmarks}")}{if(tags, " {tags}")}
With this patch, the above can be simplified to:
{separate(" ", node, bookmarks, tags)}
The function is similar to the already existing join(), but with a few
differences:
* separate() skips empty arguments
* join() expects a single list argument, while separate() expects
each item as a separate argument
* separate() takes the separator first in order to allow a variable
number of arguments after it
