Dispatch Plot improvements

Pull Request Description

Closes #322

Several updates to DispatchPlot:

Colors for a single component are the same across resource plots.
Color schemes updated to increase clarity and distinguishability within each resource plot
If the data has 3 resources, it keeps it all on one plot; otherwise, it puts 2 axes per figure and makes more figures
Adds hatching to extend the number of components that can be represented. Hatching is only used once the first set of colors are exhausted, at which point it loops through the colors again with each new hatch. This allows for (10x9)=90 components to be represented. If over 90 components are present, a warning is raised.
Removes title() modification on component names (but keeps "_" to " " swapping)

See examples below.
