Display many UI messages at a time
|Reported by:||alec||Owned by:|
In UI we've got messages of type 'loading' that are displayed until some action finished, e.g. on AJAX response. We've got also other messages (error, warning, notice, confirmation) that are disapear after some (short) time. Attached patch changes behaviour of displaying messages, so we can see many messages at a time. Messages of type 'loading' are grouped by label, so e.g. we have one 'Loading...' message even if many actions are run in parallel.
Patch doesn't handle all situations e.g. some forms submitting, where loading message is displayed continously, this changeset will also not backward compatible with some plugins that are using set_busy().
