[dev] Fixes in <ActionBarSearch /> and <ActionBarActionsButtonDrawerOption />

[groberts314]

• Action Bar Search
  • Pass a search.onClearClick passed into column options prop passed to <Page.ActionBar /> into <ActionBarSearch />'s onClearClick prop (so, you know, we can actually use it! =)
  • Fix ESLINT where possible, otherwise suppress the warnings and errors with comments, all throughout src\modules\actionBar.js
• Action Bar Buttons
  • Fix some issues with onClick bindings for the sub-options
  • Fix an issue having to do with positioning and trying to click a sub-option. In some cases the click first propagated to a different parent option that is visually "underneath" the sub-option but is apparently occupying that position! Thanks to @morethanfire for the simple fix (suppress "pointer events" when the colliding parent option is hidden)
  • Better code and styling support for disabling options and sub-options
  • Fix some ESLINT issues
• Demo Page
  • Add more options and sub options to Demo Page, with click handlers on everything logs a distinct message to the console for each thing that is clicked.
  • Also add a disabled option and a disabled sub-options.
  • Fix all the ESLINT issues (and in the process newer React component code organization style per Airbnb Style Guide)
