Add dummy method MessageListItem::messageListItemDummyMessages() to allow xgettext to add possible sources to POT files.
Mark a few i18n issues as FIXME as well as some messages for which the use case was not clear to me.
Merged some code on multiple lines into one.
Translator documentation added.
Remove superfluous whiteapace.
- "To" drop-down list now defaults to showing "Select recipient:" instead of the first person on your list, reducing liklihood of accidentally sending a message to the wrong person.
- When there are no mutual subscribers to send to, instead of an empty list the list now shows 'No mutual subscribers.'
In both cases, attempting to send when the default is selected displays an error message.
I'm not disabling form elements in part because our themes right now don't show disabled button state correctly; we might want to tighten that up a bit more once fixed.
Minimised form_notice markup by removing unordered lists. There is a minor CSS
rule reassignment done by changing the selectors. There is no visual
change in the final result.
