Brick color scheme in calibration plots and other small changes

[ricardarosemann]

• Adopt the Brick color schemes in calibration plots and additionally include specific color for "no change" renovation flows, both via mip::plotstyle().
• Flexibilize the framework to generate calibration plots: Now allows to pass facets and extending the y-axis to zero can now be inactivated.
• Correct output file name and one error message when generating the plots.

Looks good. Just wodering about the local path...

Sorry for not spotting this earlier. But can we avoid this local path?

[ricardarosemann]

Thank you for pointing to this. This is usually overwritten by plotBRICKCalib() and only applies if the .Rmd file is executed directly. But still doesn't look very nice. I'll pass the current working directory instead.

I also fixed a naming inconsistency (function plotBRICKCalib() vs. file name plotBRICKcalib.R), restricted the dplyr import to the required functions and adjusted further defaults in the header of the .Rmd file.

I noticed that knitting the .Rmd file directly does not work properly, because it cannot find readBrickSets() (I guess because it is not exported). But I figure this is a very rare use case, so I don't think this will be a problem.

Thanks you!
