Subject: [PATCH 1/2] Added try/catch into unescapeuri()

In the current version unescapeuri() gives an error if the %... character is an invalid base 16. However some url parameters can have %... as part of their value.
For those cases the function now gives a warning but returns the string without changes and doesn't throw an error.
