feat($resource): support an unescaped URL port

The colon character is used to identify parameters in $resource.
This meant that we had to escape the colon used in a port.
It turns out that this is not necessary if we assume that parameter
names cannot consist of only digits.
If the parameter consists only of numbers, then it's a port.

Closes #2778
