Tidy up, #1457, visualisation for execution plan view
Revert partial "TEIIDDES-1845 remove embedded help plugin"

This partially reverts commit a4393ab16bacf334110ca6c9bc9b46780b6e5816.

* Restores original version of Designer Linux launch file.
Spelling mistake in TeiidExecutionService
Updates Target platform

* Updates target to integration stack 4.1.3.Final
Runtime client feature not included in updata site categories

* May lead to problem with installation since this feature will never be
  selectable in eclipse
Updates the feature dependencies

* Re-computes the plugin requirements of each feature

* Ensure that the org.jboss.ide.eclipse.as.feature is a dependency of the
  designer, runtime and client features. Since the jboss as71 plugin seems
  to be required to connect successfully to jboss 7.1 servers its never
  actually imported explicitly by any plugin hence causes connection
  failures with eclipse installations.
