Make Search Profiles more intelligent to multiple users

[dpalic]

as requested here: https://github.com/znuny/Znuny-DashboardWidgetSearchProfile/issues/1

a feature is missing on the SearchProfile to make it more convinient to multiple users. E.g.

• me/my as owner is missing
• maybe there are more fields, which require such a behaviour, I will extend on finding them
