Failure in update or package install shouldn't break process

[Narcis Garcia]

1. If "apt-get update" fails to find some file, UCK breaks all the process, and this shouldn't happen, because sometimes the sources.list in the ISO can have obsolete entries, or bad added entries in a later rebuild.
An alternative could be a warning/asking message.

2. If "apt-get install" fails on language packages, UCK breaks all the process, and this also shouldn't happen, because in this way, an ISO with previous package problems cannot be repaired. For example, first rebuid and customize an ISO installing/removing packages, and someone fails to complete configuration (example: qemu); then the new ISO is generated, but cannot be rebuilt with UCK because the wizard will receive an error code on each "apt-get install"
An alternative could be a warning/asking message.
