Moving the following changes into git

"Dave Kirk just added a bunch of stuff but he's not too sharp on Git so i have it in a zip here....

You can download the build directory from http://dl.dropbox.com/u/9273778/build.zip

    You can now add multiple stylesheets to the project (defined in the project.properties file) and they will be concatenated into 1 file, with any default stylesheets defined in the default.properties file being added at the end.

    Adding new 'pages' (html, php, etc) is handled in the same way and the script should iterate through any files listed here and update the css / javascript references as per the original script

    I have also added the ability to define 'environments' for the build process as this fits in with the way I work. The original targets still exist, and run the same functions, however each target now has a prod, test and dev environment too. This has come at a as it requires using the ant-contrib library and due to the way Ant works you can no longer use the depends model, and the sub targets have to be called with antcall.

Here is how the environments work:

    * dev (default) - Increases build number, cleans and copies the build and optimises any images if the target originally did
    * test - Runs everything that the original target did, however it does not strip the console.log or profiling parts
    * prod - Runs everything the original target did

    To run it you simply use ant <target> -Denv=<environment>

ant build -Denv=prod

    If you don't provide the env variable it will use the development environment, but that would be pretty easy to change to run another environment as default.

    Like I say, it could probably still be improved no end but it is getting to the limits of Ant without writing a java library with extra tasks, which I may look at in the future.."
oops, forgot the jar

thumbS.db. lol. thx  rizkysyazuli
removing disabled mod_pagespeed reference. it doesn't help us out much.

I would much rather promote usage the build script rather than mod_pagespeed. I didn't find anything in there that was particularly useful for us..

i wrote more about it here: http://groups.google.com/group/html5boilerplate/browse_thread/thread/4c832ffcef0da433
Merge branch 'build' of https://github.com/AD7six/html5-boilerplate into AD7six-build
