• Adding hc_theme_sparkline_vb, hc_theme_hcrt themes.
• boost module is FALSE by default.
• Modifying highcharts_demo(), adding caption and credit texts.
• All vignettes were moved from the package to favor to avoid CRAN check NOTE
  and warning. The content was moved to the new website of the package.
• htmlwdgtgrid.css were removed from the yaml of highcart hchart widgets

  Now hw_grid add htmlwdgtgrid.css automatically.

  not htmlgrid.css and 2) browsable -set as TRUE the default value- so now
