#6688 dark theme

[piorek]

• menus in plot and data grid
• Data grids styles after sorting
• spark ui style after connecting (alignment is off)
• plot text item color (black text and arrows)
• resize thumb missing in plots

this loses the fonts?

[piorek]

probably incorrectly resolved merge conflict. Its ok now.

This is looking good but I found a few crashes. In PlotFeatures.ipynb, the Text cell crashes with:

index.js:12319 Uncaught (in promise) TypeError: Cannot read property 'substr' of undefined
    at Object.createColor (index.js:12319)
    at r.format (index.js:80390)
    at new r (index.js:80382)
    at Object.createPlotItem (index.js:50529)
    at Object.formatModel (index.js:50285)
    at Object.standardizeModel (index.js:49942)

    at M.init (index.js:37516)
    at initStandardPlot (index.js:64851)
    at index.js:64756

the main Charting.ipynb example fails the same way.

and the %%spark magic crashes with:

java.lang.RuntimeException: java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.String

[piorek]

I'm not able to reproduce those errors

[scottdraves]

spark magic crash does not appear on my other machine,
but the substr of undefined problem looks real.
please work with LM tomorrow to straighten it out.
