Attempt to normalize patches files names

[Jacques Le Roux]

After a short discussion at https://issues.apache.org/jira/browse/OFBIZ-2445 and following Ashish's last comment I 'd like to 
suggest a new contributor best practice for naming patches in Jira issue.
The name would be featureDescription_OFBIZ-number.patch where featureDescription  would be "full Jira issue title if its small" and 
"part of title if its big" along with the OFBIZ-number as suffix.
Other suggestions may be found in the Jira issue above. It seems that this 
should help commiters in their work...
WDYT ?
