v0.2.4

New features:

• You can now load easily from gists. The format is: gist:<gist id>[@<sha hash>]/<file>.js
• A url cache, so if two scripts have the same dependency from the same url, it won't fetch it twice.

Changes:

• <script> tags will now be loaded synchronously, as they would be if they were as a normal <script> tag. This also supports the async attribute, but it's kind of useless as it wouldn't block loading anyway.
• Inline <script> tags get a url for debugging, its format is inline-legume:<module name>
