Added tag cubicweb-squareui-version-1.0.1, cubicweb-squareui-debian-version-1.0.1-1, cubicweb-squareui-centos-version-1.0.1-1 for changeset 8726628e1bfd

So it's not in the middle of openid/login/register links.

Added tag cubicweb-squareui-version-1.0.0, cubicweb-squareui-debian-version-1.0.0-1, cubicweb-squareui-centos-version-1.0.0-1 for changeset 186bfea9c12a

The core of this patch is to have the following layout ::

  <nav class="navbar">
    <div class="container">
      <div class="navbar-header">
        [header-logo components]
      </div>
      <div class="collapse navbar-collapse>
        <div class="nav navbar-nav">
          [header-left components]
        </div>
        <div class="nav navbar-nav navbar-right">
          [header-right components]
        </div>
      </div>
    </div>
  </nav>

This prevents the column from collapsing on top of one another if the
screen width is too small. This effectively keeps the 2 column layout at
all screen sizes.

This allows the page content to stretch all the way to left/right window
borders. All width restrictions are lifted.

Added tag cubicweb-squareui-version-0.3.8, cubicweb-squareui-debian-version-0.3.8-1, cubicweb-squareui-centos-version-0.3.8-1 for changeset cae67c4b203a

The X-UA-Compatible directive forces IE9+ to go into IE8 mode, which
never actually behaves like IE8 and actively breaks everything (b0rked
layout, missing text, dysfunctional forms, etc).

Also remove html5.js as it's not shipped anywhere.

Added tag cubicweb-squareui-version-0.3.7, cubicweb-squareui-debian-version-0.3.7-1, cubicweb-squareui-centos-version-0.3.7-1 for changeset 30c90c063940

This allows writing components using cwtags which monkeypatches
CubicWeb's UStringIO for correct operations.

This fixes a regression introduced by commit 45b3eb604765.

The web browsers are quite tolerant to this but not the (x)html
validators. It is necessary to fix this for e.g. automatic web tests
not to fail.

This is not in __pkginfo__ nor in debian/control and I could not find any
reference to this in the code.

Added tag cubicweb-squareui-version-0.3.6, cubicweb-squareui-debian-version-0.3.6-1, cubicweb-squareui-centos-version-0.3.6-1 for changeset 2474c306a055

Fixes a regression introduced by commit 530993d25fe5.
