Fixed ordering of submit events, inline submit events & inline data attributes.
Fixed ordering of submit events, inline submit events & inline data attributes.

Inline submit events (i.e. <form onsubmit="...">) should always fire FIRST & the submit.hijack event should always fire LAST.

Wrapped inline event in a lexically scoped function to prevent global insertion.

Changed order of optionsData merging so that inline data attributes are always added last.
