plugin fr.cnes.analysis.tools.analyzer should not depend on org.eclipse.ui

[opcoach]

This plugin is a core plugin without any UI concerns.

It must absolutely not depend on org.eclipse.ui. If we remove this dependency there is only one error on : PlatformUI.getPreferenceStore() to get ANALYZER_EP_CONTRIBUTOR_CHECK_ID.

It is better to use the IEclipsePreferenceService class like this (example found in FileHelper.class) :

	String defaultLineDelimiter = Platform.getPreferencesService().getString(Platform.PI_RUNTIME,
			Platform.PREF_LINE_SEPARATOR, platformDefaultLineDelimiter, null);
