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

#require test-repo execbit

  $ cd "`dirname "$TESTDIR"`"

look for python scripts without the execute bit

  $ hg files 'set:**.py and not exec() and grep(r"^#!.*?python")'

look for python scripts with execute bit but not shebang

  $ hg files 'set:**.py and exec() and not grep(r"^#!.*?python")'

look for shell scripts with execute bit but not shebang

  $ hg files 'set:**.sh and exec() and not grep(r"^#!.*(ba)?sh")'

look for non scripts with no shebang

  $ hg files 'set:exec() and not **.sh and not **.py and not grep(r"^#!")'
