Bugfixes and optimizations

Small release, mostly to fix the Unknown Host dialog popping up all the time, making SWGAide unusable on a computer without Internet

• Fixed error that made the Unknown Host dialog pop up constantly when no Internet connection was available. Instead, it will now popup once when loss of Internet is first detected and on any subsequent loss of connection (but not multiple times per loss)
• Added code documentation
• Replaced a lot of raw types with parameterized versions
