[PATCH] Modified the default git help message to be grouped by topic

[Scott Chacon <schacon@gmail.com>]

It's difficult to process 21 commands (which is what is output
by default for git when no command is given).  I've re-grouped
them into 4 groups of 5 or 6 commands each, which I think is
clearer and easier for new users to process.

As discussed at the GitTogether.

This makes the 'git' (with no arguments) command look like this:

This won't automatically update with the common-commands.txt file,
but I think it is easier to parse for the command you may be looking
for.
