WebServices: Reflected change of Simple Web Service dialog

Removed SimpleRESTWebServiceTest because Simple Web Service Dialog can't be
used to create JAX-RS service. Removed SampleRESTTestBase (no more needed).

Renamed SimpleSOAPWebServiceTest to SimpleWebServiceTest because the test
cover the whole wizard now.

SimpleWSWizard reimplemented to RedDeer and moved to ws.reddeer plugin.
Its superclass was changed to NewWizardDialog which do function of NewSimpleWsWizardAction.
Because of that, the NewSimpleWSWizardAction was removed.
WebServices: Updated JBossWSRuntimePreferencePage

Inherits from WorkbenchPreferencePage instead of PreferencePage because
the concrete preference page should be a subclass of WorkbenchPreferencePage.
Also refactored
WebServices: More RedDeer (API, requirements) - updated MANIFEST and README.md

Fixed assertion of delete operation in CreateJAXRSResourceTest

Added @JBossServer / @OpenPerspective annotation to each test class that needs
server / opened perspective in order to prepare test classes to run with RedDeer
suite

Updated MANIFEST.MF and README.md - imports requirements (JBossServer,
OpenPerspective)

JAXRSFacetTest uses just RedDeer (removed usage of SWTBotExt and SWTBot)

AnnotationPropertiesTest uses RedDeer to assert text in editor

More RedDeer in JBossWSPreferencesTest, CreateJAXRSResourceTest, CreateJAXRSApplicationTest, WSTestBase
Removed unnecessary links to SWTBotExt / SWTBot and refactored
