I tried to maintain the current scroll position
within a list however this caused many issues
to do with outdated data, as well as performance issues.
Now we are going back to just refreshing any list on focus.
Closes#184
This simplifies our codebase greatly by
only having a single stack navigator and
a single drawer navigator. Previously we had
a stack navigator for every main page on the drawer.
I was considering adding weight tracking,
so then this graph page would include body
weight graphs. Meaning it's not really
recording the "best" of anything.
It currently only shows the best on the list
page anyway.
