core: - individual parameters managed through sqlite

- new asyncGetParamA method, which allow to get parameter for a not connected profile
	  	==> individual parameters are cached in memory when the profile is connected, but must be accessed
		    though sqlite else, and that must be done asynchronously
primitivus:
	  - profile manager updated to use asyncGetParamA

/!\ still broken, need more work before being able to run again
