Tips - bunch of updates

Vacation ended, new semester started and wiki comes to life. My beloved Qt Creator slowly reaches 1.3 point. There is a rumor about releasing final version before the end of the year. Meanwhile I trialed the latest snapshot - Qt Creator Crew definitely doesn't sit around doing nothing. They even introduced color schemes, so I had to update my dark theme. Afterward I fixed description of making SOCKS proxy transparent, because previously used transocks_ev often stalls, but its replacement, redsocks, works flawlessly. Lastly, three days ago I added MinGW gcc related tip/workaround for problem of __declspec(dllexport), __stdcall and lacking leading underscore in Export Table.
