fixed automatic url decoding of query entries
cleaned up parsing of query entries without a value
renamed send to request in \arc\http\ClientStream - consistent with \arc\http
renamed $request to $query for clarity
fixed a few bugs and warnings
- spaces are now encoded to '+' instead of '%20' in \arc\url\Query
- parsing of query entries with no value is fixed
- query entries are now properly decoded
- removed incomplete (and no longer needed) method call
