Remove the bower stuff
I think we can simplify the project removing the bower stuff
Are there plans for this?
Note: We need to downgrade stylelint-config-vaadin back to 0.1.4 now (since that version works with bower and HTML imports) to fix CSS lint task in master. But when we get rid of bower and HTML Imports (in demos and docs etc.) we probably need to upgrade stylelint-config-vaadin to latest (currently 0.2.10) again.
This is definitely something we want to do at some point (move from bower and HTML imports to npm and ES modules) but it's currently not high priority (mainly since it only affects demos and docs here I think) and it's not trivial since we need to make sure we still have a similarly (or better) working demo and documentation setup.
