Fixed hg help screen for prompt

hg help would report "(no help text available)" for the prompt plugin
because the package comment was located after the future import. This
patch fixes that problem by relocating the future import to after the
package comment.

Usage
=====

The `hg prompt` command takes a single string as an argument and outputs it.
Here's a simple (and useless) example:

    :::console
    $ hg prompt "test"
    test

Keywords in curly braces can be used to output repository information:

    :::console
    $ hg prompt "currently on {branch}"
    currently on default

Keywords also have an extended form:

    :::text
    {optional text{branch}more optional text}

This form will output the text and the expanded keyword **only** if the
keyword successfully expands. This can be useful for displaying extra text
only if it's applicable:

    :::console
    $ hg prompt "currently on {branch} and at {bookmark}"
    currently on branch default and at 
    
    $ hg prompt "currently on {branch} {and at {bookmark}}"
    currently on branch default 
    
    $ hg bookmark my-book
    
    $ hg prompt "currently on {branch} {and at {bookmark}}"
    currently on branch default and at my-book

You can give the `--angle-brackets` option to use angle brackets for keywords
instead of curly brackets. This can come in handy when combining a simple
prompt string with more complicated shell functionality (like color
variables):

    :::console
    $ hg prompt "{currently on {branch}}"
    currently on default
    
    $ hg prompt --angle-brackets "<currently on <branch>>"
    currently on default

Take a look at the [keywords][] documentation to see all the keywords
`hg-prompt` supports.
