* Could only have one alias before. Subsequent aliases overrode the
previous ones. Now multiple aliases work.
* Fix BLACKLISTED_MODULES. Previously, modules were listed in the
generated documentation despite being blacklisted
* Deprecated modules form extras were showing the (E) tag and not the
(D) tag. Reversed that now (Probably not necessary to also show the
E tag).
* Sort the deprecated modules alphabetically in the Category docs as
well as the list of all modules
* Optimization: Previously rendered the modules to rst twice once in all
group and once in individual categories. Fixed to only render them
once.
* Add fireball to blacklist and remove async_status (as people need to
use that).
