Added checkbox and made TCP proxy optional
Removed DNS logging for new release

Dev only!
Bumped up version to 1.2.2.0
Re-enabled TCP proxy

Just realized that disabling the proxy will break your WhatsApp because
the DNS proxy redirects c*.whatsapp.net to your machine.
It will now no longer try to decode the message instead.
Added build 1.2.2.0

- Added intercepted media download (mms*.whatsapp.net)
- Disabled TCP decoding by default, click checkbox on the left to enable
(too many issues)
- Added password extraction from HTTPS for TCP proxy
- Fixed stream invalidation when no password is set
- Removed always setting Content-Type header in HTTPS proxy
- Added DNS proxy error handling and restart on crash

Possible bugs (not sure if my HTC HD2 running WP7 is just fucked or
actual bugs):
- Requests to WhatsApp's crash report server always return error code
417
- Video downloading is borked (can someone test this?)
