Rename Event::MouseMoved to Event::MouseMove

[teddemunnik]

As discussed in #821, this renames MouseMoved to MouseMove for consistency with web API's.

Let's fix this link to enum.Event.html#variant.MouseMove while we're here.

Sure, fixed :)

I wonder if we should start keeping a list of breaking changes somewhere for release notes. 🤔

Yeah I think it might be a good idea to start a CHANGELOG.md which gets modified with PRs. Every PR can then add a short description of its change to the changelog with a link to the PR. Changes can be grouped by e.g. breaking changes/new features/bug fixes. Generally would be pretty easy to gather the changelog this way. The only somewhat tricky thing is that whenever some behavior gets reverted or modified and there hasn't been a druid release yet, then this revert/modify PR should also remove the older changelog entry.

for now i'm going to use a label for breaking changes, which will solve one of my problems.

Consistency is good, and this is a good time to get these changes in.
