Redmine

It's not good to use "Redmine" for every page meta description. Not only for SEO.

Check this (clicked "Like" on Redmined website):

• For project "Overview" page Redmine shoudl use project description
• For Wiki Redmine should use Wiki content
• For news Redmine should use news content
• etc

I believe there should also be a way to set meta description in layout files like it is done for HTML title (e.g.):

<% meta_description(l(:text_some_description)) -%>

P.S. The issue is related to #3121 and #225.
