Allow dots in app names (closes #260)

App names may now contain dots, such as sneak.berlin: runs of lowercase letters and numbers joined by single dots or by hyphens, 2 to 63 characters. Docker accepts every such name in the app's image name, upaas-<name>; a dot needs a letter or number on both sides because Docker requires it. The rule also keeps a dot off either end, so the name is safe as a directory and log file name. The new and edit app forms use the same pattern. Their old one was not a valid regular expression under the flag browsers compile it with, so browsers ignored it. Model: opus-5-5
