Distmaker updates

[totten]

Everytime an issue comes up that involves our tarballs, I look at "distmaker" ( https://github.com/civicrm/civicrm-core/tree/4.4.5/distmaker/dists ) and shutter:

• There's a lot of copy-pasted code. Sometimes the code is identical; sometimes tweaked; sometimes, further on, there are overrides to cancel-out effects from the copied code, but you can't recognize that unless you pay very close attention. To make a new change, you change generally have to apply the change to each copy (ie 5 times).
• When invoking distmaker, it runs "git checkout" which negates local changes or local branches -- and which puts you in the awkward position of either committing changes before you've tested them or hacking distmaker. This is partially fallout from maintaining D6+D7, and it's partially my fault (for not fully understanding distmaker and making it worse during the svn=>git migration).

So I've refactored a bit ( https://github.com/civicrm/civicrm-core/tree/master/distmaker/dists ):

• DRY/Dedupe: Most of the code now lives in helper functions like "dm_install_core" (which copies civicrm-core files) and "dm_install_drupal" (which copies the Drupal-integration module).
• Direct Execution (without git): If you want to build a particular tarball without triggering "git checkout", just call the build-script directly (eg "cd distmaker/dists; ./joomla_php5.sh"). However, if you want to build all the tarballs(D6+D7+SK+J+WP), then some "git checkout"s are necessary; use the master script instead (eg "cd distmaker; ./distmaker.sh all")

These changes have been applied to 4.4.next and master.

Very cool!
