Issue 55

Decided to start working on #55 
So i implemented a possibility to collect a bunch of messages and then displaying them at once in one Message dialog. I think this is a step in the right direction.

Also i have problem. I tested the functionality of the message-accumulation feature by dropping in random messages. Can anyone test the actual application with the VST-plugin? I can't seem to get the VST-plugin to build on my debian stable.... probably libwine-dev-bleeding-edge-stuff.


The only criticism (although minor) is that the function name `logError()` is a bit misleading when the error is thrown up to the GUI level and used for collection.   I'd like @diizy's opinion on this, but when someone is determining how a message makes it to `MainWindow` it may not be obvious that a `logError()` function would populate a list for a graphical component.

Perhaps the "collection" wording should also be part of this function name?
