Adium 0.74 available

Adium 0.74 has a short list of changes but is a strongly recommended upgrade for MSN users. A mistake during the libgaim update for 0.73 led to major stability issues while connected to MSN; this is now corrected.

Don't forget that our source code host, penguinmilitia.net, will donate $5 to Adium for each new customer who mentions Adium when signing up. We're thankful to them as always for the generous space and bandwidth they donate to the project.
