Improve the Flag feature

There are some things we could do to improve the Flag feature:

1. Capitalize the entries from the drop-down list
2. Remove the "alt" entry from the drop-down list or wite more text for it; I don't know what it stands for; "Alternative reason" ?
3. Improve the Status column from the Administration section (http://localhost:8080/xwiki/bin/admin/XWiki/XWikiPreferences?editor=globaladmin&section=Forums) -> rename "inprogress" to "In progress" and capitalize the other entries
4. Display an error when flagging a topic if the user doesn't have his Email settings instead of getting an error in the console: XAFORUM-146
