Add settings and all prototypes to the export of data done. Settings
are needed for a settings GUI to function, while prototype data would be
useful to display any sort of information about things from the game.
Convert code indents to tabs to be consistent with the rest of the
JavaScript code. This commits covers all of the lua code, some of the
hand written JSON code and the lone HTML and CSS files that were not
using tabs.
Fix incorrect serialization of control characters to \xHH escapes since
JSON only support \uHHHH escapes, and serialization of infinite and NaN
numbers.
Move the export and clusterio mod code to the slave package and fix the
path used for them. Refactor tests to use temp/tests/ as the cwd when
running integration tests in order to ensure paths to lua code are
correctly handled.
