look into angular material themes

[pickled-dev]

I've really struggled with the angular material themes. On the one hand, it seems like the only way I'm able to really have any control over angular material without venturing into ng-deep territory, but, on the other hand, even with ng-deep there still seem to be some places I can't really reach.

Take, for instance, changing the font of the place holder text in the material forms. I can't seem to change the font on those. But I imagine that if I used some themes I could actually change the font.
