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

u = uimod.ui()

print('% creating repo')
repo = localrepo.localrepository(u, '.', create=True)

f = open('test.py', 'w')
try:
    f.write('foo\n')
finally:
    f.close

print('% add and commit')
commands.add(u, repo, 'test.py')
commands.commit(u, repo, message='*')
commands.status(u, repo, clean=True)


print('% change')
f = open('test.py', 'w')
try:
    f.write('bar\n')
finally:
    f.close()

# this would return clean instead of changed before the fix
commands.status(u, repo, clean=True, modified=True)
