This uses more arguments in the GET request for mod versions on the
Modrinth API, filtering what versions can be returned, decreasing load
on Modrinth servers and improving a little the time it takes for the versions to be
available to the user.
This also removes the now unneeded check on correct modloaders in
ModrinthPackIndex, since it is now filtered by the Modrinth server.
Lastly, this adds a couple of helper functions in ModModel.
The checks used are roughly the same as the ones proposed in the
clang-tidy PR (except perhaps that I used modernize-* instead of listing
them individually,though I don't think this caused any readability
detriments).
In ModrinthModel.cpp and FlameModModel.cpp I ignored the
modernize-avoid-c-arrays one, mostly because making the sorts array an
std::array would most likely increase the code complexity because of the
virtual function. Aside from that, the static_cast warning from
Application.h was not dealt with, since it's not in this PR's scope.
This also adds some comments around ModModel.cpp and ModPage.cpp to add
some ease of reading the code.
Also move some things from headers to cpp files.
This is done so that 1. ModAPI behaves more like an actual API instead
of just a helper, and 2. Allows for more easily creating other mod
providers that may or may not use network tasks (foreshadowing lol)
Moves all things related to creating the URLs of the mod platforms
that go to network tasks to a single place, so that:
1. Maintaining and fixing eventual issues is more straightforward.
2. Makes it possible to factor out more common code between the
different modplatform pages
This creates a hierarchy in which ModPage and ModModel are the parents
of every mod provider, providing the basic functionality common to all
of them.
It also imposes a unique .ui file (they were already equal before, just
duplicated basically) on all mod providers.
