Subject: [PATCH] Updated actions/init.lua

Added actions@hyperlink_exec. Responsible for acting upon an execution
call from keybinding. Function gets the contents of the buffer and makes
call to actions@suburl.

Added actions@suburl. This function specifically performs a substitution
of text in a buffer line and replaces it with a hyperlink, formatted as
markdown.
