Profile introduction

Introduce Profiles to store sets of values that describe a system/device.

These profiles are held by a target, getting rid of much of the information
stored in the Build-/Run-/DeployConfigurations, greatly simplifying those.

This is a squash of the wip/profile branch which has been on gerrit for a
while, rebased to current master.
