Revision on https://github.com/odoo/odoo/commit/a87d761fdbf345ada5dc93e0a686b08a0f5a0417
From the UX/UI changes above, we also changed the style for empty
inbox and starred in Discuss.
There are two issues with the empty boxes message:
1. The text is not centered at all (one word per line,
and everything is stuck on the left-side of the screen)
2. The style is inconsistent with nocontent message on search
In this commit, inbox and starred use the same style as the no_content
message from a search. The style of the nocontent from a search has been
slightly changed to mimick the intended style for inbox and starred:
- centered text
- title is in bold 125% font size
- other text is not in bold, 115% font size.
