Have a way to know if a SFDC sync filter is established.

[Grégoire_Miche2]

When taking over a Marketo instance synchronized with SFDC, there is no simple way to know whether a sync filter is set. The only way is to ask support

This idea is that it should be possible to easily know in admin -> salesforce whether or not a sync filter is set, and if so, which fields are being used.
