New hardware for Retrace Server

[Michal Toman]

Hi everybody,

we have just replaced the old (and slow :)) host running Retrace Server 
and ABRT server with a new one. The most significant changes for users are:
- Retracing now runs in memory, which means faster generating of 
backtraces (by an order of magnitude)
- Reports from CentOS 7 are now accepted and cross-referenced with Fedora
- ABRT Server now marks problems as probably fixed when a newer build 
exists and did not experience the problem in 14 days

Some more features will probably be deployed soon - new webui, filtering 
of tainted reports and displaying user comments - stay tuned :).

Please let us know in case anything does not work.

Michal & ABRT Team
