Omnijar enabled for trunk - default builds switch to "flat" chrome

Just a quick note to say that I've just landed the switch to omnijar on 
trunk. I'll be blogging about this later today.

However, the main thing to note for people building Thunderbird is that 
the default chrome format has been switched from jar to flat. This means 
that the chrome files will not be zipped into jars, but symlinked on 
Mac, Linux and copied on Windows.

I'm not sure if a clobber is necessary, but it will at least clean out 
the old .jar files from your chrome directory.

More information here:

 From people I've spoken to it is better to develop with flat chrome as 
you basically just need to restart Thunderbird to pick up UI changes 
rather than restarting with a make step in-between.

If you do for some reason want to keep building with the jar format, 
then you can just add:

ac_add_options --enable-chrome-format=jar

to your .mozconfig.
