issues: change "fixed version" to "target version"
I feel that the "Fixed version" select box that appears for issues after having created a version is nonsensical, especially for a user filling out a new issue.
- Past tense is just wrong (in any language?)
- The person filling out the issue will likely have no idea what version the problem will be addressed in.
- I'm guessing that for most software development, the "Fixed version" will not ever be set when the issue is closed.
