add a "priority" field for each locale and use it as the default sort order

[chrishofmann]

not exactly sure how we will assign the priorities , but we can experiment with various options.

this will allows us to group locales in more flexible ways. currently we have troubles communicating about the following groups of locales so maybe to start we might use:

p1 = locales we have shipped in previous releases p2 = new locales that we have committe to for the next release p3 = locales that has been requested by a partner p4 = other locales that localization teams are working on in hopes of getting shipped

I think we should group locales, with tags or something. I don't like Px, it pretends that we'd do things in particular orders or so. Also, different folks read different things in them.

The current implementation is just a field with a number associated to a locale code, I can use a different approach with tags, but the requirements should be a bit more precise then :) We can also have both, but we should also not put too much information into the table otherwise it will be dificult to read and understand.

I put values for priorities in 924a750ffd3bf0206011a57c78227f4a982a7c03 The table is still sorted by default by locale, keeping the bug open until I change that.

Locales now sorted by priority by default in 3c6bf4938cd16473fb232be25d5fae0e31f7b46e
