New Revision: 10887

URL: http://svn.gna.org/viewcvs/relax?rev=10887&view=rev
Log:
The number of maximum lines in the relaxGUI log window is limited to 1000
lines.

relaxGUI calculation crashed during local tm calculation due to too many
lines in the relaxGUI log window. Therefore, the maximum amout of numbers is
limited to 1000 as discussed with Edward d'Auvergne
(https://gna.org/bugs/?15173).

A new function to limit maximum lines in relaxGUI log windows was introduced
into controller.py.
