At the moment, translating Jira requires a tedious search an replace. We need to make it easier for users.

For example:
The fact that each properties file has a different order of properties can make translation a hassle.

For example to translate the word Resolve to french you to:

1. Open JiraWebActionSupport.properties
2. Find the key resolveissue.resolve (line 1330)
3. Open JiraWebActionSupport_fr.properties
4. Search for key (line 962)
5. Translate

Step 4 could be completely omitted if the key was on the same line for both properties files. It would also make it much easier to see what translations are missing.
