Fixes #67 #68 #69 - Changed navbar and added games admin.

Changed templates dir in settings_local. Templates were not rendering
correctly.
Changed password reset template just for style changes.
Changed style of edit-profile template.

Added First and Last name to profile. It is duplicated in auth.user but
still added in profile as auth is only used for logging in.

Solved edit-profile issue with redirect directive.

Added permission in games model for admin usage.
Now only admin users may enter the games/admin URL.

Base template was modified. Now logged in users show a dropdown menu
with options. If user is administrator, then extra menus are shown.
