+nominate UI needs a big rework

The +nominate UI needs a fair bit of work:

The page title doesn't tell me which project/distro I'm targetting for.

The initial paragraph changes completely depending on whether you have privileges to target or not, providing more introductory text if you do have privileges. This isn't how it should be; I'm more likely to need to have it explained to me if I'm Joe Random hitting the nominate button.

The page mentions releases everywhere; it actually nominates or targets for series.

"Release manager" isn't a term used elsewhere in Launchpad. It's in fact the driver.

It gives me a horribly right-aligned list of artificially-capitalised series names with checkboxes next to them, explaining that they are series that can be "nominated" (even though it'll actually target to them, as I have sufficient privileges on that project). Perhaps it means to ask me to select those that I want to target to.

It then finishes with a nice generic "Submit" button. It should in fact be "Nominate" or "Target"
