Filtering in Users module & more sorting options

It would be helpful to use filters in the users module (just like in the feedback and support modules) to find the right users.

Some example filters include:

• Users vs Leads

• Tags

• Emails

• Names

• Segments (already can)

• Country

• User ID

• First Seen, Signed up, Last seen

• Custom synced data (e.g. subscription status, plan, etc.)
