updated emulationLayer to use WidgetLayer (not Widget, which is b0rked)

default.cpp is broken, because there is still no new widget (coming
soon...)

    We use a refreshing algorithm here that has been adoped from rxvt/kvt.
 
    By this, refreshing is driven by a timer, which is (re)started whenever
    a new bunch of data to be interpreted by the emulation arives at `onRcvBlock'.
    As soon as no more data arrive for `BULK_TIMEOUT' milliseconds, we trigger
    refresh. This rule suits both bulk display operation as done by curses as
    well as individual characters typed.
    (BULK_TIMEOUT < 1000 / max characters received from keyboard per second).
 
    Additionally, we trigger refreshing by newlines comming in to make visual
    snapshots of lists as produced by `cat', `ls' and likely programs, thereby
    producing the illusion of a permanent and immediate display operation.
 
    As a sort of catch-all needed for cases where none of the above
    conditions catch, the screen refresh is also triggered by a count
    of incoming bulks (`bulk_incnt').
 */

    - evtl. the bulk operations could be made more transparent.
