[tw5] Parsing arrows from shorthand

[Anjar]

Hi all,

To improve my workflow a bit, I used the the dash-parser as template to 
replace ->, -^, -. and -< with →, ↑,  ↓ and ←, respectively. Just sharing 
in case it could be useful for others!

Best,
Anders

Wiki text inline rule for arrows. For example:

-<
