Eye: Set 500x500 as default content area

Pupil Cam1 uses 4:3 resolutions. Pupil Cam2 and Cam3 use 1:1 resolutions. As all Pupil Core and VR/AR add-ons are shipped with Pupil Cam2 and Cam3 cameras, we adjust the default eye window size to a 1:1 content aspect ratio. The size of 500 was chosen s.t. the menu still fits.
