Create Rest Serializers and Views for UserTool model

[destos]

Most changes should be in the tools app
Views should go in an api_views.py if not yet created.

This endpoint can be used by all authenticated users to view, update and create tools with the relevant visibility options. Mainly for external application integration with tools that are stored within toolhub.

When creating a new UserTool, the requesting user should automatically be used as the owner.
The API should also allow you to supply a user to be used as the owner if they have the correct permissions. This would be a custom permission and possibly tied to staff user status.

It should attempt to save as many of the fields as possible. Might have to move photo upload to a separate endpoint.
