This adds support for reading configuration from file, env support is still there and legacy env variables will still work, but flags are now following config schema, so they don't match old flags.
Having a config file allows to express more complex configuration options, which is needed for some feature requests.
use linkifyjs to make all URLs in the annotation clickable, but since it requires us to stop escaping html when rendering annotation object let's first manually escape it to prevent rogue alerts with malicious annotations from executing <scripts> and other ugly things in user browsers
setFilters() will trigger fetch of the new alerts with updated filter, it's being called after each filter is added to the filter bar, so each added filter ends up with AJAX call to /alerts.json, this means that when someone clicks on a history entry with complex rule it will trigger multiple subsequent requests. What's worse first request will have bigger response body (since it filters less) so it's likely that it will finish after the next request, leaving invalid alerts on the grid. This disable setFilters() if we apply filters in batch mode.
Show search icon for search history elements and provide a separate entries for the default and saved filter.
Default & saved filter are always rendered on the bottom, if they are non-empty.
This allows to quickly select recently used filters from a dropdown. It also shows default (configured by unsee admin) filter and the saved one (saved by the user to a cookie)
We use flatly theme for bootstrap while bootstrap-tagsinput bundles a css file that follow vanilla style, create a less version and use it instead of the css one bundles with bootstrap-tagsinput.
typeahead.js allows to customize class names used for UI elements, but bootstrap-tagsinput doesn't support passing that and is no longer maintained, so we need to follow default typeahead.js classes.
Right now if user starts typing & then starts pressing backspace we pause but never resume, because stopping pressing backspace is ignored when resuming.
This will tell webpack to add a hash to all bundles filenames, we generate script tags for loading those and inject them as templates. No more forced cache bypassing
