Pull version from pkg resources
Bump the version that raises DeprecationWarning

Since anything that is listed as 1.2 should technically be removed in
1.3 (and it raises anyway), bump the version that raises to 1.3, and add
todo's to remove them in 1.4.
Remove exception property from exception

As noted by the TODO, this was due to be removed in 1.3.
Add TODO notes to remove this functionality in 1.4
Remove test code no longer required

Since the .exception property has been removed, we no longer capture any
warning.
Test deprecation of functionality
Change from_string to from_bytes

This allows us to avoid a deprecationwarning being raised and makes the
test compatible with version 1.3 or higher of WebOb.
