Blender 2.81 Fix

Fixing the broken Display Dropdown Menu because it moved in 2.81.

Thanks https://github.com/zocker-160 bringing this up.

Blender2.8-RenderButton v2

Second version with added Display options.

Added on request by #1

No idea how how Blender does with updating addons, it has a higher version number now but it might be advised to just delete the old version in the addons settings and add this one after.

Blender2.8-RenderButton v1

First release of the RenderButton addon.

Only includes the Render and Animation button.
