Allow for country name change over time

[robertocarroll]

Show Palestine (State of) from now on and for 2014-2015 but Palestinian Authority for previous years.

• [x] Edit dictionary.json so that country names use their name in English as the key, instead of the country code that they currently use.
• [x] Change countries in data.json to caps so it is clear they are dictionary references.
• [x] Change amnesty.js so that country names are looked up using this new key.
• [x] Add dictionary.json entries for “Palestinian Authority” and “Palestine (State Of)”.

Reference for point 3:

data_country.name__localised = dictionary.getTranslation(data_country.id);
.html('<div class="title-text">'+ dictionary.getTranslation(d.id) + '</div>');

Search / autocomplete isn't handling the change of name.
