Update dependencies from README to the required introspection library

[Adi Roiban]

Running ./autogen I got the following error
configure.ac:11: installing `./missing'
couchdb-glib/Makefile.am:107: HAVE_INTROSPECTION does not appear in AM_CONDITIONAL
couchdb-glib/Makefile.am: installing `./depcomp'
desktopcouch-glib/Makefile.am:36: HAVE_INTROSPECTION does not appear in AM_CONDITIONAL

It looks like I am missing some "introspection stuff" but there are no hints in the README.

On Ubuntu it seems that installing 'gobject-introspection' will make autogen pass... but ./configure does not detect the introspection support.

Here is a excerpt from running ./configure

checking whether to build gtk-doc documentation... no
checking for gobject-introspection... no
configure: creating ./config.status
config.status: creating Makefile
[snip]
config.status: executing depfiles commands
config.status: executing libtool commands
configure:

 couchdb-glib configured:
 ------------------------

 version: 0.7.0
 oAuth: yes
 introspection: no
 bindings: Mono (no)
Now type `make' to compile couchdb-glib

Also, it looks like the uuid-dev package is required.

I think you may need libgirepository1.0-dev to enable introspection but I can't really check right now. Confirming that you need a uuid-dev package to build couchdb-glib

After installing libgirepository1.0-dev I got the introspection enabled in couchdb-glib.
