(bug 31068) Configure namespaces for Azerbaijani Wikibooks

This patch fixes an error in the set-up of NS_PROJECT and
NS_PROJECT_TALK on azwikibooks. Here's what happens:

1) I manually moved all pages from namespaces 104 and 105
to NS_PROJECT and NS_PROJECT_TALK on-wiki after being
granted temporary adminship by steward Vituzzu;
2) These two namespaces are empty now, and I'm removing
them with this patch;
3) I'm setting up namespace aliases from the currently
existing 'Wikibooks_müzakirəsi' to NS_PROJECT_TALK as well
as from 'Wikibooks_talk' to that same namespace; 'Wikibooks'
is set up as a default redirect in the config already;
4) I'm setting up wgSiteName as 'Vikikitab', which will also
be the new name for NS_PROJECT; NS_PROJECT_TALK will use
the definition from MessagesAz.php ($1_müzakirəsi).
