Added support:
1. Environment variable `WOODPECKER_DELETE_MULTIPLE_RUNS_ON_EVENTS` (Default pull_request, push)
2. Builds will be marked as killed when they "override" another build
Rewrite of the UI using Typescript, Vue3, Windicss and Vite. The design should be close to the current one with some changes:
- latest pipeline in a sidebar on the right
- secrets and registry as part of the repo-settings (secrets and registry entries shouldn't be used as much so they can be "hidden" under settings IMO)
- start page shows list of active repositories with button to enable / add new ones (currently you see all repositories and in most cases you only add new repositories once in a while)
