introduce config file versioning

A new entry in the config file ".version:" stores the current version of the
config file. The '.' at the beginning of ".version" shows that this is a
somewhat hidden (read: internal) entry and it makes the line easy to spot and
prevents clashes with regular config entries.
The first use of this is to reset all decoder priorities to 0 (= use default)
so that we hopefully won't have problems like the qtv decoder clash any more.
