Added TotK images

[freshefisch]

I have added the images for every compendium entry of totk with the following properties, as discussed in #30 (comment) :

• 280x280 resolution
• 24 bit
• File name matches the entry's name (to lowercase and space replaced with underscore), HOWEVER see below
• Size ca. 80-130 KB each
• Total size ca. 55 MB

There is one possible issue I could already spot:
The image: value of weapons that end with (new) are missing an underscore right before (should be _(new))!
This seems to be because the same is true for the names of these items. So for example the entry gerudo_scimitar (new) is missing an underscore aswell (should be gerudo_scimitar_(new)).

Edit: It's actually all entries that have more than one space in the name, see my reply below.

It would be very easy to change the filenames of these couple images, but it's probably best to correct the entries' names. Unless this is on purpose.

Actually the name issue with the underscores in the name seems to be the case for all entries that have more than one space!
For example demon king ganondorf (2nd form)
Image url is: [...]/compendium/entry/demon_king ganondorf (2nd form)/image?game=totk

Here there is actually 3 underscores missing, only the first one was replaced! This probably happened because at some point replace was confused with replaceAll !!!

As of right now this doesn't seem to cause any issues, but with the images it probably will, since the filenames of the images have all spaces replaced with underscores.

Maybe there's something wrong with these two lines? But .replace in python should replace all occurences. In javascript you'd have to use regex though.
