Use a separate folder for the TypeScript build for Node.js in the dist
folder. This makes each type of build consistently have its own output
folder instead of being interleaved with the Node.js build.
When creating temporary files use the pattern `.tmp.ext` instead of
`.ext.tmp` to be consistent with Factorio which creates `.tmp.zip` files
during saving.
If patching fails this will leave a `.tmp.zip` file in the instance saves
directory which is ignored by the default save selector.
Resolves#486.
Allow modules to include a module_exports.lua file in their root which
will cause the file save/modules/module_name.lua to be generated
pointing to the exports file.
Map locale files located at locale/{lang}/{file} in a module to
locale/{lang}/{module-name}-{file} in the save. This additionally
support a shorthand notation by mapping locale/{lange}.cfg to
locale/{lang}/{module-name}.cfg.
Resolves#500.
