1.5.0 Release

• Add a new stacks pattern.
• Tooltip pattern: Add a new ajax-data-type option that makes it possible to use markdown content as AJAX source.
• Update Makefile to install npm modules as needed. This makes it possible to completely bootstrap and build Patterns using make from a clean git clone.
• Checked flag pattern: make sure the fieldset classes are updated correctly when changing the radio button selection. This fixes #348.
• Bumper pattern:
  • Add new selector option to allow overriding which elements must be updated.
  • Add new options to specify which classes much be added/removed when an item is (http://patternslib.demo/un)bumped.
• Depends pattern: also update dependencies on keyup. This makes sure actions happen without forcing a user to move focus away after modifying a text field.
• Rewrite the slides pattern to use the new Patternslib slides library, replacing shower.
• Fix event handling in the sortable pattern. This could result in unexpected behaviour in Firefox.
• Add a new forward pattern.
• Add a missing dependency on jquery-ext to the registry module. This fixes errors invoking the scan function when using a Patterns bundle.
• Validate pattern: perform validation when submitting forms via AJAX.
• The argument parser can now disable configuration inheritance if needed by a pattern.
• The select-option pattern has been merged into the checked flag pattern.
• Checked flag pattern: add new API to control select and checkbox elements.
• Do not handle exceptions during Patterns initialisation and transforms if a patterns-dont-catch query string parameter is present.
