* Replaces all references to isIgnitionError with isGhostError
* Switches use of GhostError to InternalServerError - as GhostError is no longer public
There are places where InternalServerError is not the valid error, and new errors should be added to the @tryghost/errors package to ensure that we can use semantically correct errors in those cases.

- Simplified the yaml parser implementation to take in a single parameter, this move will allove to simplify the logic in the route settings + opens a door to unify handling with redirects yaml parsing!
- We loose the "filename" from the error information but that was a generic "routes.yaml" anyway and would be thrown only when somebody uploaded a routes.yaml file (no real added value).
- The debug statement should be moved to contain related filepath+other info to the calling module instead
- An additional error handler was borrowed from the redirects yaml parsing logic that was introduced in a referenced commit - it still makes sense to keep it for routes.yaml configuration
- i18n is an old pattern we are getting rid of in favour of tpl
- after removing i18n from helpers, there wasn't many usages of i18n left in the frontend, this removes whats left!
- this was done on a branch at the same time as Naz's commits removing i18n from the settings-related files
- hence some of these changes are minor amends to add additional messages/change names, rather than just straightup i18n->tpl
- it's a merge of both our refactors :)
