* fix modal widths - sellModal now using input instead of dropbox

* upgrade to bootstrap 4.0beta

* include package-lock changes

* fix app menu dropdown position

* upgrade bootstrap to beta2 (was missing grid offset and other fixes) - refix header menu position

* fix tags popup (auto width to max not working) - fix filter panel width (adding width: 100% works until max-width)

* fix package-lock?
