Bug 12775: Suggestions should be ordered by anyone

Currently only the suggestion manager can order from accepted
suggestion.

This patch set to default the ability to show all suggestions when
ordering from a suggestion.
2 links "show only mine" and "show all" permits to filter/show all
permissions.

Test plan:
Create an order from a suggestion and verify you are able to see all
suggestions by default.
Verify the "show only mine" link works as expected.
