Add support for anonymous comments

Browse source 
This allows for removing users without also removing the corresponding
comments. Instead, all comments from deleted users will be displayed as
"Anonymous comment".

Upgrading
=========
From 2.3.1 to 3.0.0
-------------------
1. Drop the user ID foreign key from the "PackageComments" table:
`ALTER TABLE PackageComments DROP FOREIGN KEY PackageComments_ibfk_1;` should
work in most cases. Otherwise, check the output of `SHOW CREATE TABLE
PackageComments;` and use the foreign key name shown there.
2. Add support for anonymous comments:
----
ALTER TABLE PackageComments
MODIFY UsersID INTEGER UNSIGNED NULL DEFAULT NULL,
ADD FOREIGN KEY (UsersID) REFERENCES Users(ID) ON DELETE SET NULL;
----
From 2.2.0 to 2.3.0
-------------------
