updated tinycon

Tinycon has been updated with Retina screen support, I put in the new version.
Here's the original PR to that repository which has been merged:
https://github.com/tommoor/tinycon/pull/46

The current version of tinycon in RES will always use the low resolution icon, even if there's a 32x32 one available. This makes the reddit favicon ugly on a Retina device if you use RES. No other work is needed in RES to avoid this than to update tinycon.
