* FEATURE: Add ignored user list to the User's preference page
## Why?
Part of: https://meta.discourse.org/t/ability-to-ignore-a-user/110254
We want to add list of Ignored users under or along with the muted users preferences section.
This way Users can find and update their list of ignored users.
## UI

## Open questions
Two of many options to represent a list of ignored users is that we can:
1. We can represent the ignored user list as a table with the ability to `un-ignore` but NOT to add new ignored users.
2. We can keep it functioning as the `muted user list` where you can `un-ignore` or `ignore` users.
* Adds warnings to the "Edit Category" dialog
* Doesn't hide the "Security" tab on the "Edit Category" dialog anymore. Instead, it shows an explanation why permissions can't be changed.
* Makes the category name translatable
* Hides the category name from the edit dialog (it can be customized by overriding the translation)
* Creates a translation override if the category has been renamed in the past
Sadly there is no clean way of detecting a keyboard is connected to an iPad
If the keyboard is connected we want to disable all the touch related hacks
on iOS
This allows iPad users to specify they have a keyboard connected. Setting
is per device.
* UX: make composer resize work on touch devices
This also replaces a vendor dependency with a small built-in resize mechanism.
* Make blue bar's larger padding specific to touch devices
This attribute is used when a submit button is out of a form. It makes it explicit which form this button is submitting.
It's currently used in our login modal form.
Negative option was leading to a fair amount of confusion, going forward
if we want to allow selection of emails from user selector it must be
supplied with `allowEmails=true`
This corrects a regression in 1f4ace4f which broke invite by emails and
start PM to email
This commit also:
- removes [+ New Topic] behaviour from share, this feature has been duplicated in composer actions, months ago
- introduces our new experimental spacing standard for css: eg: `s(2)`
- introduces a new panel UI for modals

Chrome 63 and up start ignoring `autofill="off"`
Per: https://bugs.chromium.org/p/chromium/issues/detail?id=468153#c164
> The tricky part here is that somewhere along the journey of the web autocomplete=off become a default for many form fields, without any real thought being given as to whether or not that was good for users. This doesn't mean there aren't very valid cases where you don't want the browser autofilling data (e.g. on CRM systems), but by and large, we see those as the minority cases. And as a result, we started ignoring autocomplete=off for Chrome Autofill data
So to work around this decision we now explicitly say: autocomplete="discourse"
when we don't want Chrome to randomly fill in addressed (aka. always)
Fixes composer warnings when: a) mentioning groups ("By mentioning @group, you are about to notify x people...") and b) mentioning users in a PM ("You mentioned @user but they won`t be notified...")
