templater: implement _hybrid.__contains__ so that ifcontains can accept dict

d8fb835376d1 is fine for "{revset()}", but "i.values()[0]" does not work if
each item has more than one values such as "{bookmarks}".

This fixes the problem by using list.__contains__ or dict.__contains__
appropriately.

     template expansion works like this. a map file contains key=value
     pairs. if value is quoted, it is treated as string. otherwise, it
     is treated as name of template file.
 
     templater is asked to expand a key in map. it looks up key, and
     looks for strings like this: {foo}. it expands {foo} by looking up
     foo in map, and substituting it. expansion is recursive: it stops
     when there is no more {foo} to replace.
 
     expansion also allows formatting and filtering.
 
     format uses key to expand each item in list. syntax is
     {key%format}.
 
     filter uses function to transform value. syntax is
     {key|filter1|filter2|...}.'''

   $ hg log --debug > log.out
   $ hg log --debug --style default > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
 Default style should also preserve color information (issue2866):
 
   $ cp $HGRCPATH $HGRCPATH-bak
   $ cat <<EOF >> $HGRCPATH
   > [extensions]
   > color=
   > EOF

   $ hg --color=debug -v log --style default > style.out
   $ cmp log.out style.out || diff -u log.out style.out
   $ hg --color=debug --debug log > log.out
   $ hg --color=debug --debug log --style default > style.out

 Missing non-standard names give no error (backward compatibility):
 
   $ echo "changeset = '{c}'" > t
   $ hg log --style ./t
 
 Defining non-standard name works:
 
   $ cat <<EOF > t
   > changeset = '{c}'
   > c = q
   > EOF
   $ hg log --style ./t
