Merge pull request from @Spuds. Makes whitespace and other coding styles consistent. Update version to 1.6.3.
Bug fix: links with submenus were unable to be followed in Firefox since 1.6.1. Quickfix for this will mean issue #30 will need to be reopened until I get a workable solution.
Previous commit message should have referred to #31 not #30. Updated changelog.
Didn't get the previous fix right.
jQuery Plugin Registry doesn't like such granular version numbers. 1.6.5 it is, then.
Provide alternate zip link in readme.
