Decode MS packet before testimony recorder regex

- Fixes an issue with the testimony recorder checking for >[statement], where due to AO encoding, special characters would improperly match the regex. For example, "%[statement]" would become "<percent>[statement]", thus matching against >[statement]. This commit decodes those characters first.

- Adds AOClient::decodeMessage() for decoding a QString.
