Standardize on 'blog' and 'network' in the Network Admin
|Reported by:||nacin||Owned by:|
In code, we should use blog and network, and avoid site where possible. When site is used, it should be legacy only and should refer to the network.
Visible file names are fine, e.g. my-sites, site-info, etc. This also does not affect strings. WP_MS_Sites_List_Table should become WP_Blogs_List_Table though.
