Adds a site setting to allow multiple solutions to be accepted in the solved plugin. Behavior without the setting enabled should remain as before these changes. ### Model/DB changes Previously, solutions were stored in a `SolvedTopic` model backed by the `discourse_solved_solved_topic` table, which pointed to a topic id, a post id, an accepting user id, and optionally a timer id for a timer to auto-close the topic after a set amount of time if configured. Now, the `SolvedTopic` model drops the post id and accepting user id, but still points to the topic id and the timer id (there will only be one timer per topic), and adds a has_many relationship to a new `TopicAnswer` model. The `TopicAnswer` model backed by the `discourse_solved_topic_answer` table points to a `SolvedTopic` id, a post id and accepting user id, with one `TopicAnswer` for each accepted solution post. References to `topic.accepted_answer` or `topic.solved.accepted_post` have been changed to `topic.accepted_answers.first` or `topic.solved.topic_answers.first.post`, etc. Updated all specs/tests and added new cases for the multiple solutions mode. Several references in other build-in plugins are also fixed in this PR. ### Allow multiple solutions mode These changes add the site setting `solved_allow_multiple_solutions` which is disabled by default. When disabled, behavior should be as it was before these changes. Users can not accept multiple solutions for a single topic. If a post in the topic is already marked as a solution, then the "Solution" button is hidden, and if a user still accepts a different solution then the original solution will be unaccepted. When enabled, users can accept more than one solution for each topic. Even if a solution is already accepted, other posts still show the "Solution" button. Users can still unaccept any accepted solutions. If a topic has multiple solutions, each one is displayed as a summary under the OP using the existing component to represent the summary. For displaying the solved checkmark icon, filtering, etc, a topic is considered solved if it has at least one solution. ### UI Added a PostExcerptAccordion component which displays post excerpts in an accordion style with a header and expandable/collapsible items, and that component is used to render the solution post(s) under the OP. The first item is displayed expanded while the others are collapsed, by default. The expanded items are truncated based on a number of lines calculated from the `solved_quote_length` site setting, with a "read more" link to view the full post.
