Consider making this a dismissible/minimizable alert

Technically by being 'removable' once the issue is resolved (upgraded PHP) this is fine per the plugin guidelines. That's not this. This is a thought about keeping the WP Dashboard usable.

Seeing as this is not something that everyone can fix in one click, and its very LARGE (which IMO it should be), it might be prudent to be less invasive on global usability. My thoughts are to allow it to be dismissible but:

1. Keep an alert in the WP Admin Bar
2. Keep a number on the upgrade menu (and show the message on the upgrade panel)
3. Keep a one-line alert "Upgrade PHP!" which expands when clicked
4. Keep a BRIGHT RED tab by options/support with the information

Mind, WP needs a notification control center overall but that's a different horse to beat.

I'm spitballing here, since there needs to be a balance between UPDATE PHP!!!! and making sure it's not ignored.

We could make it so that if you minimise it, it appears on all pages? :)

Show the minimal alert on all pages you mean?
