Bug 1091575

Description of problem:
In man 5 firewalld.zone, typos in rule section:
- "general rule structure" has superfluous "/" at end of opening rule tag;
- "rule structure for source black or white listing" has same error;
- error causes rule tag to be prematurely closed;
- following the documented structure in a zone file causes firewalld to fail to load the zone file;

Version-Release number of selected component (if applicable):
- firewalld.noarch-0.3.9.3-1.fc19

How reproducible:
- always

Steps to Reproduce:
- man 5 firewalld.zone
- use documented rule structure in zone file (eg, to blacklist a particular IP)

Actual results:

- following the given structure yields zone file rules like:
<rule family="ipv4"/> <source address="11.11.22.22"/> <drop/> </rule>

- which fails to load, with journals like
firewalld[30037]: 2014-04-26 11:05:39 ERROR: INVALID_RULE: no element, no action: rule family="ipv4"
firewalld[30037]: 2014-04-26 11:05:39 ERROR: Invalid rule: Action outside of rule
firewalld[30037]: 2014-04-26 11:05:39 ERROR: Failed to load zone file '/etc/firewalld/zones/public.xml':

Expected results:
- zone file loads and source address is blacklisted

Additional info:
- works correctly once superfluous "/" is deleted from initial rule tag
- typo in man documentation
