Changed deploy-management to parent pom, bumped version

Changed deploy-management directives to parent pom and bumped
the version number to 0.0.3-SNAPSHOT. Those modules that do not
need to be deployed (template and stub-demo) override the
deployment setting. Also bumped jetty-server in stub-demo to
newer version.
Moved all ville-styling to be included grom vexer-stub

Removed any explicit styling info from vexer-stub-demo (ie. including
chameleon-theme) and moved all that to vexer-stub. The styles are
pulled from vexer-stub in vexer-stub-demo using Vaadin-style inclusion.
Vexer-archetype includes all its general styles from vexer-stub

After the vexer-stub-demo were changed so that all the general stylings
come from vexer-stub, also the vexer-archetype for generating new
vexer-projects must be changed accrodingly.
Add ville-standardutils git-based artifact-repo to pom

Ville-artifacts should be added to some centralized Ville-repo
sooner or later, but using github as the repo should be good enough
for testing
