there were several issues - see rev 87aa1e0fcb086d82243e517310c192a049275582
and the one before for defatils.
essentially, a loop trying to make room for text being added was not finding
enough lines to strip off and was therefore running infinitely.
I've also fixed scolling in the process, which I am guessing had never been
tested in this particular edge case.
to testers: feel free to play with dwt/test/RichTextBoxTest.cpp - interesting
combinations to test these cases:
* REPEATED_TEXT = L"ABC\n"; REPEAT_COUNT = 16384;
* REPEATED_TEXT = L"A\n"; REPEAT_COUNT = 16384;
* REPEATED_TEXT = L"\n"; REPEAT_COUNT = 16384;
* REPEATED_TEXT = L"AAABBB"; REPEAT_COUNT = 16384;

Title:
Sending a lot of empty lines to main chat makes DC++ to hang
Status in DC++:
Fix Committed
Bug description:
If i send 15000 empty lines into main chat from another client, DC++
will hang (sometimes i need to do it twice). When i then restart DC++
i can see a message '65766: Buffer overflow' from the chat history. So
if the hubsoft have no line limit you can hang a lot of DC++ clients
in the hub.
I'm running DC++ 0.865.
