fritzfla.sh seems to be defunct, so switching to link provided by openwrt.

To avoid possible copyright claims, replace the vendor or product logos
with a generic picture.

Also update the current x86-generic picture to use only free fonts.
While the previously used font seems to be Swiss-911 or Alternate Gothic
No. 2, which are both non-free, use the free Nimbus Sans Narrow font.

Without the if it was possible that images[vendor] was
undefined because their was no image available for that
vendor. And then `Object.entries(images[vendor])` resulted in:

Uncaught TypeError: Cannot convert undefined or null to object

And this led to the problem that no device at all was shown :(

Fixes d45019d1 ("app: filter vendors without images for enabled device categories")
Fixes #118
Closes #122

Fixes #118

The picture currently used for the Ubiquiti Rocket shows both the Rocket
and Rocket Titanium. This splits the combined picture and uses each
picture for the corresponding device.

This loads the vendor list for the dropdown menu from the vendormodels
structure. This way, only vendors for enabled device categories are
displayed.
