Setting the global locale is no longer needed, as Boost.Filesystem and
Boost.Locale are no longer used. All Boost dependencies are now
header-only.
Install language packs on Travis to ensure that the Turkish and Greek
locales exist for testing. Now that only header-only Boost libraries
are used, just download and extract the Boost archive on Travis.

If a plugin's masters are all present, this makes the sorting logic for
Morrowind match the other supported games. If a plugin's masters are
missing, use the plugin's total record count as the override record
count.
Plugins with missing masters cannot be loaded by the game, reducing the
impact (if any) of the probably-inflated record counts. It's better for
LOOT to be able to sort a slightly wonky load order if there are missing
masters than for it to fail completely, as such plugins may be present
for development and testing reasons.
Sorting doesn't work as for other games, because esplugin can't tell if
a plugin contains override records, so returns 0 for their count, so no
overlap edges get added.
