Option to not use "+" in escape_url

[Hannes Voigt-Georg]

Hi
following problem:
I'm implementing this uri-template spec. I could realy use a version of escape_url without the "+" for whitespace, since this behavior is defined in the spec. Rereplacing the pluses afterward with "%20" is not a good option as this more than doubles the runtime, which is too expensive imho.

If i write a method escape_url2 with this behavior, would you pull it?

We already have this:

>> EscapeUtils.escape_url(" ")
=> "+"
>> EscapeUtils.escape_uri(" ")
=> "%20"
