Float edits with a spinner are by default sized to fit their full
min-max range of possible values, so this makes min and max default to 0
and 100 (like it'd done internally in wx) instead of -DOUBLE_MAX and
DOUBLE_MAX.
Note that this does change the behavior of lua dialogs, but does not
contradict existing documentation or specification. It should only
affect scripts who either disobey the specification by specifying only
one value out of max/min, or scripts displaying these large float edits
by specifing a step, but no max or min.
In preparation for switching to LuaJIT, which doesn't support PUC Lua's
thing of using C++ exceptions for lua_error.
Requires replacing all uses of lua_error (and things calling lua_error)
with custom versions that throw an exception instead and adding an
exception -> lua error wrapper at all C++ -> Lua boundaries.
This requires shuffling a bunch of stuff around to get a CLI lua
executable that uses an automation-like environment, but that's
something that'll be nice to have in the future anyway.
Busted indirectly depends on lfs and we currently can't use external
binary modules, so add a copy of lfs to the repo and build it with
Aegisub.
