bump minit-ver cache buster to match 1.0.0 (current master)
Skips script handles from being added to async queue if they're excluded via 'minit-exclude-js'.

Before this, all external scripts were unconditionally being 'asynced', which might not be always wanted.
I've had other external scripts enqueued (think ad-servers and/or similar stuff that must not be asynced
due to document.write) and unconditional asyncing broke them. This was a quick fix, as it gives devs
back some control over 'asyncing' - it might even help fix #21 (or at least fix one part of the problem)
Moved apply_filters outside the foreach loop. Duh.
Merge pull request #29 from zytzagoo/allow-async-exclusion

Scripts excluded from Minit should also be excluded from async
