Rework MessageDelegate to be mostly a cpp class. This allows us to only load the components that are actually needed saving memory.
In testing using memtest it saved ~30% versus the current implementation.
Create a simple app that puts a number of events into a simple timeline which can be used to verify future memory optimisations
When Neochat is built with tests on you should find the app at ~/kde/usr/bin/timeline-memtest assuming ~/kde is your kdesrc-build directory
