Support so print can print only important text.
SVG modified to use display:inline/none based on overlay True/False and
a symlink to make it easy to change to a completely seperate svg if that
is not optimal.
SVG added layers to split text and graphic so graphics can be easily
hidden and printed.
Closes: #38
* Switch to showing the PNG version by default, as this reflects what
will actually be rendered and sent to the printer
* Include the greyscale filter
* Include the twemoji font we'll use for rendering the badges
* A TimeOrStockLimit limit can apply a limit to a whole category, or
to specific products
* This report was only counting the products directly listed
* Take advantage of the new all_products property to include the
products indirectly listed as well as those directly listed
It's common to need to query the fill list of products covered by a
Flag - whether directly, or by being in an included category.
Add an all_products property which does this.
* Add a greyscale filter to text for more accurate preview
* Always default to SVG preview as it's the most accurate (cairo
doesn't do a great job of handling custom fonts when it converts to
png/pdf)
* Always use roboto font.
* Undo some of the debugging done early in this series of patches
* Add ability for a user to preview their own badge
* Add a template for the LCA2018 badge
* Whether a Flag is disable-if-false or enable-if-true is a very
important detail
* But one that's easy to get wrong
* And it's hard to spot problems without inspecting every single flag
This change adds the Condition into the various admin list views, so
that it's easier to scan them all for problems and look for inconsistencies.
"Next" is green, indicating that it's the default path, the way
forward. "Back" is available but blue.
For extra consistency, the initial "Get ticket" button is now also a btn-success
Let's say you've just installed symposion for the first time, and
you're running the intial `./manage.py migrate`
In that circumstance, there isn't an auth_group table. Naturally this
means you get Some Errors when trying to look for a particular group.
This change handles that error and drives on.
