data.override_sample_rate:

    - store resampling rate in globalv.CHANNELS
gw_summary: don't archive alongside --html-only
gw_summary: process 'Overview' tabs last
Tab.get_channels: allow return of old plots
SimpleStateTab.build_inner_html: fix typo
html: use navbar-brand in stead of navbar-text
navbar: improved dropdown groups
tabs layout: added sizing scheme

    - if layout entry is tuple, (x, y), scaffold for x plots sized as if
      they were in a row for y plots
      E.g. (1, 2) will print a single plot with 50% width (using
      bootstrap columns)
