Cannot add Kit environment variables using SDKtool

During installation, Qt Embedded adds cross-compilation kits using sdktool addTC, addQt and addKit. Now if we want to set environment variables for the Kit, it does not seem to be possible.

1. There is no "--environment" option to the addKit command
2. Even if adding the environment as an extra key-value pair option, e.g.
   addKit ... PE.Profile.Environment QVariantList:FOO=42,BAR=/dev/null
   it will be added ok to the SDK profiles.xml, but creator ignores that setting (i.e. fails to copy it)
