Beta label for certain Finders

As we launch Finders which may be considered in Beta, we want a way to
display this on a per finder basis. We set this in the metadata in
Finder API, which gets sent the content store as part of the details
hash.

This commit sets this on the Finder object and displays the beta label
if this is true.

Beta label for certain Finders
Explain Publishing API requirement

With the move to use the content store, a bunch of steps were needed to
get the App running the first time round if you hadn't done a data sync
recently. This commit adds a section in the README to explain what to
do.
Remove FRONTEND_TOOLKIT_DEV flag handling

Nobody on this project is using this flag at the moment (or has ever used it, for that matter), so removing it from the Gemfile as it kind of threw me earlier when I was trying to debug my project not using the right version of the frontend toolkit gem

Remove FRONTEND_TOOLKIT_DEV flag handling
Remove link underlines from finder item headings

In long lists of links, underlines add a lot of visual clutter, making it hard to read long headings like those found here.

Fix contrast and border on iOS

It appears safari on ios8 respects border/background-color settings, which means that the white+no border were rendering these inputs practically invisible on ios8

This commit adds a class to both of the input[type=text] so that we can appropriately scope the white background/grey border to text inputs only. I've used a class instead of input[type=text] so that it works in ie6 too.

With this added we no longer need to overwrite the width and the border which means ios does the default contrasty thing that we want.
Remove li scope

don't need to scope these styles to an li so remove it.
Remove font handling here

We don't need to handle font sizes for responsive because the @include deals with it.

Fix checkbox contrast
Removing instruction text above filters

We shouldn't have to describe how the UI works like this.
If it's not clear in and of itself, we're doing something wrong.
Let's see how users get on without this instruction.
Reenable display of js-enabled button elements

This was added in a refactor commit (7dbeca7) and had the effect of hiding the
sign up subscription button. Not sure if that's whats intended, but it should
definitely be there now.
Add checkboxes on email signup.

This depends on the correct choice data format being in the content store so
shouldn't be deployed until after the associated change in finder-api.
Improve styling of checkboxes to match govuk elements.
Update finder frontend email signup to match actual prototype.
Remove quiet helptext

This was not on the prototype and nobody in user research had difficulty understanding that they should enter an address.
Remove full stop

I don't think 'Select the email alerts you need' is a sentence so, so removing this.
Removing unused class
Give the legend some bottom padding
