Use larger CDN image size instead of 128px

[ChillFish8]

Issue

Currently the CDN avatars are loaded at 128px, this is fine for the default theme however this puts a large limit on customisability especially if you want to spice up your bot page with a bigger icon etc...

For this i would suggest the following:

• Give developers the choice of selecting the avatar size (Harder to implement and probably not worth it)
• Load bot avatars on main page to be greater than 128px, personally i would suggest 256px as it's probably the best balance of quality and file size.
• remove all custom css to spite our whims ¯\(ツ)/¯

Example of where it causes issues: On bot page with the image size scaled to fit nicer, set to 256px h/w

Example of where it causes issues: On bot page with the image size scaled to fit nicer, set to 256px h/w manually changed quality

Other potential or existing solutions

Currently i think the only maybe possible way to fix this is by spoofing the CSS of the image itself in order to override it with a new source, this is a pretty bad idea though as it's just yet another image to load and let go wrong when the css changes or gets funky.
