QmlJSScriptConsole: Refactored ScriptConsole, added functionality.

The ScriptConsole is renamed to QmlJSScriptConsole. The console can be used to evaluate expressions during a QML application debug session. Changes: * Console can be used even when application is not on a debug break * The object context is the currently selected object in Inspector * ContextMenu has a Clear option * Multiple line expressions are supported * Traverse Command History using up and down arrow keys Change-Id: I4e1cd8763d60be43dbba395ead2a9a086d6bab7d Reviewed-by: Roberto Raggi <roberto.raggi@nokia.com> Reviewed-by: Kai Koehne <kai.koehne@nokia.com>
