config: update default URL regex

Browse source 
The old one is in some cases too liberal. The new one is stricter in
two ways:

1. The protocol list is now explicit, rather than matching anything://
2. Allowed characters are now limited to the "safe character set", the
   "reserved character set", and some from the "unsafe character set"

Furthermore, some of the characters are restricted in how/when they
are allowed:

1. Periods, commas, question marks etc are allowed inside an URL, but
   not at the end.
2. [ ], ( ), " " and ' ' are allowed but only when balanced. This
   allows us to match e.g. [http://foo.bar/foo[bar]] correctly.

Closes #2016
