commands: fix documentation of report.post
node.xml: fix firewall database schema

The order by clause on the vcatindex view was failing
the quqery in commands/__init__.py getCategoryIndices
which had a select ID leaving out the two order by
elements

Mysql error was:
(1356, "View 'cluster.vcatindex' references invalid
table(s) or column(s) or function(s) or definer/invoker
of view lack rights to use them") "SELECT ID FROM
vcatindex \n\t\t\t\tWHERE catindex='calit2-110-119-102'
and category='host'"

to trigger this error you can simply run
rocks run firewall host=localhost
tests: add test suite for test firewalls commands
built: run 'make install' to install commands files in your rocks system

If you are developing feature in commands now you can simply run
make install
to copy all the commands files in your current rocks installation
