flexdashboard 0.6.0

This release adds integration with the new {bslib} package, making it much easier to customize the overall appearance of the dashboard (and/or upgrade to Bootstrap 4). See the new website's new article on theming to learn more.

Possibly breaking changes

• The smart argument was removed from flexdashboard::flex_dashboard since it was removed in rmarkdown 2.2 (relatedly, we now require rmarkdown 2.2 or higher). (#301)
• The window.FlexDashboard.themeColor JavaScript object property is no longer available. Resolving of theming accent colors should now be done server-side via {bslib}'s dynamic theming tools. (#305)

Improvements & fixes

• Close #343: Fix an issue with order of dependencies with shiny_prerendered following previous changes in rmarkdown - rstudio/rmarkdown#2064. (#344)

• Closed #315, #321, and #286: DT::datatable() now fills its container correctly inside of flexdashboard::flex_dashboard(). (#322)

• Closed #310: An .active class may now be added to a particular .tabset tab to control which tab is shown by default. (#311)

• Closed #306: A .tabset-pills class may now be added to .tabset to render pills instead of tabs. (#307)

• Closed #297, #254: gauge() now uses justgage.js 1.4.0, allowing renderGauge() to properly update various labels and sectors on redraw. (#301)

• Closed #300: When a custom {bslib} theme is provided to flex_dashboard, gauge() and viewBox() now generate default styles to match it. (#301, #305)

• Closed #227: Fixed a bug with source_code: embed producing errors because code wasn't being escaped before being included in HTML. (#228, thanks @cderv)

• Added padding to the top of the sidebar. (#294)
