Subject: [PATCH] Move lyxerrFlush() out of singnal/slot business.

Under massive load of lyxerr<< messages we lose synchronization in ui
and messages get garbled into each other.

This patch helps a lot, note however that the problem is generally hard to
solve in multithreaded environment because from inside lyxerr there is no
way how to know that t1b should be bound to t1a when thread is switched in
unfortunated time and thread thread2 goes for his bussiness.

thread1 out<<t1a<<t1b<<"\n";
thread2 out<<t2a<<t2b<<"\n";
