[AppDB] naming convention

[Jonathan Ernst]

As discussed with Chris and others on IRC we'd like to use a new variable naming convention in AppDB code.

The proposed scheme is the following ("hungarian notation"):

handles: $hSomeHandle
integer: $iSomeInteger
objects: $oSomeObject
arrays: $aSomeArray
strings: $sSomeString
and so on.

constants will still be uppercase without prefix.

Do someone object this ?
