* soften language around daily limits and add daily
let's try to be as gentle as we can with new users
* better copy suggestion from Blake
* further copyedit improvements
When the user has not selected any tags and minimum_required_tags
is specified for a category, they get a clientside validation error
to tell them this. We were not doing the same thing when
min_tags_from_required_group and required_tag_groups was specified.
There is a category setting that enforces 1 or more tags must be added to a topic from a specific tag group before creating it. This validation was not being run before the topic was being sent to a review queue for categories that have that setting enabled.
There was an existing validation in `TopicCreator` but it was not correct; it was only validating when the tags did _not_ exist and also only happened on `create`. I now run the validation in `TopicCreator.valid?`
I also improved the error message shown to the user when they have not added the tags required (showing the tag names from the tag group), and changed the composer tag selector to not show "optional" if there are N tags required from a certain group.
* DEV: ensures stylesheet watcher isn't crashing with gems plugins
This bug has been exhibited since discourse_dev is now including an auth plugin which was loaded as a relative path instead of an absolute path, eg:
`Users/bob/.gem/ruby/2.6.6/gems/discourse_dev-0.1.0/auth/plugin.rb`
Instead of
`/Users/bob/.gem/ruby/2.6.6/gems/discourse_dev-0.1.0/auth/plugin.rb`
Let's say you want to use a gem in a plugin that has a dependencie.
You would write something like this:
```ruby
gem 'dependency-gem', '1.2.3'
gem 'amazing-gem', '4.5.6'
```
However, since when we install a plugin gem we install it in the `gems`
directory created inside the plugins directory, when it comes the time
to install the `amazing-gem`, it won't be able to find the `dependency-gem`.
This fixes that issue by adding the `gems` plugins directory to the global gem path.
Also fixed a frozen string error when specifying a source.
Headings with the exact same name generated exactly the same heading
names, which was invalid. This replaces the old code for generating
names for non-English headings which were using URI encode and resulted
in unreadable headings.
I noticed this while trying to debug slow performing ember tests.
Our docking mixin sometimes sets timers but never cancels them when
removed. I'm not sure of any errors this causes but we should be tidying
up whenever the component is removed.
The server used to respond with a generic 'error, contact admin' message
which did not offer any hint what the error was. This happened even when
the error could be easily corrected by the user (for example, if they
chose a very common password).
