Put all IOfs function into IOfs{}

[Maingron]

At this point, we have way too many and badly-named IOfs functions, which just results in absolute chaos.

The upcoming, temporary solution will be to just put all of these into IOfsV1{} (or something alike). (Not IOfs{}!)

Step 2 will be to refactor all IOfs functions (names, parameters, results) so we get an unique system and put them into IOfsV2{} = IOfs. At this point we might think about keeping IOfsV1, maybe in a separate file, for now.

Step 3 will be to refactor all IOfs functions internally, which presumably won't change names, parameters or results, but may add to them. Step 3 may be delayed for good.

Step 4 will be to move from IOfsV2{} to just IOfs{} and remove IOfsV1{} completely. At this point, the existing functions shouldn't break anymore, but Step 4 should probably be reconsidered, also since we may likely eventually upgrade to IOfsV3 (or it may be necessary to go to IOfsV2_1) or something. IOfsV3 would probably change the storage system from localStorage to something bigger and better.

We now have IOfs{} (I think it's IOfsv2{}). It's better than what we had before, and it's working pretty great. Could probably use some optimisations though.

Please use the new IOfsv2 (?) functions. Thank you!
