[IoTivity Simulator] Handling resource interfaces.

[IoTivity Simulator] Handling resource interfaces.

1. Added APIs to add and remove resource interfaces from service provider and
   tested the functionality from eclipse plug-ins.
2. Updated client controller UI to get the resource interface type
   as one of the query parameters for sending GET/PUT/POST requests.
3. This code check-in also includes the following:
	i)   Validating resource type entered by the user during resource
		 creation without RAML from eclipse plug-in.
	ii)  Minor bug fixes in native code and eclipse plug-ins.
	iii) Updated javadoc comments for Java APIs.
	iv)  Minor refactoring and optimization in eclipse plug-ins.
	v)	 Removal of unused icons from service provider plug-in.
	vi)  Removed unnecessary pop-ups for success scenarios.
	vii) Included the missing algorithm standard library file in RAML source file
         to avoid build failure.
