Add --spec to the default parameter list.

Add --spec to the default parameter list.

This simplifies some of the git-submodule stuff.  For example, deps2hooks.bat
can be changed from this:

@echo off
setlocal
set TMP_GCLIENT_FILE=.tmp.gclient
echo solutions=[{"name":".","url":None,"deps_file":".DEPS.git"}] > %TMP_GCLIENT_FILE%
FOR /F "delims=" %%a in ('call gclient hookinfo --gclientfile=%TMP_GCLIENT_FILE%') do set HOOKINFO=%%a
set HOOKINFO="call %HOOKINFO:;= & call%"
cd ..
cmd /c %HOOKINFO%
del /F src\%TMP_GCLIENT_FILE%
 
... to this:

@echo off
setlocal
call gclient runhooks --spec="solutions=[{'name':'src','url':None,'deps_file':'.DEPS.git'}]"

I think there should be a test that verifies that when --spec is passed the
gclient object ends up with the right config, and when --spec isn't passed,
things end up in the right state, too.

PS. M-A is OOO for a while, so not sure when he'll get a chance to look at it. 
It may be a while.  Do you want to try landing it before he returns from
vacation?

Yeah, I'd like to not wait; it makes a lot of the convenience scripting around
git submodules alot more... convenient.

I just realized that this change would defeat one legitimate usage case, which
is `gclient config --gclientfile <.gclient override> --spec=<spec>`.  I'll
upload another patch in a bit...
