Create a default implementation for org.rhq.modules.plugins.jbossas7.BaseServerComponent.getTempDirAttributeName instead of an abstract method

This avoids breaking the API compatibility
Bug 1069646 - Support drift for EAP domain mode

Added new drift definition templates in the plugin descriptor, targeted to monitor files in the configuration directory (ignoring *_history directories).
[BZ 1111243]  EAP6 resource adapter metrics are not shown in JON 3.2 (need :
include-runtime=true)

Added resource-adapters runtime subsystem with 'Connection Definition
Runtime' as a child resource having all required metrics.

I also a bit extended capability of SubsystemDiscovery. As
connection-definitions resources are exist a bit deeper in DMR tree I
introduced new syntax for default 'path' value. This way I avoided to
introduce just another resource type - in this case it would be "Statistics"
with path statistics=statistics

Path can look like
"subsystem=a,sub-sub-system=b/resource-type1|resource-type2"

"/" denotes : go deeper to subsystems and look for given resource types
there instead of parent resource
make messageBar float right, so it shrinks to size of displayed message and sticks on right
