Fixed ErrorBarPlot mpl2.0 compat and made it more general #1131
ErrorBars were one of the only failures in our compatibility with mpl 2.0, the difference is that errorbar caps are disabled by default and that the return signature differs. This adds that compatibility and also made the plot correctly animate ErrorBar plots with varying numbers of error bars and adds support for inverting axes on the plot allowing it to be adjoined correctly.
Ha! Yes, let's not use glob imports.
Anyway, now that is resolved, this PR looks fine and the tests have passed without needing to be updated. Merging.
