Bcml

The main purpose of this release is the substantial fixes made to map merging when mods wish to delete actors. Also improves handling of moved directories and strips line breaks from BNP descriptions.

- Fix failure to read version
- Fix blank mod list

This is the big overhaul. BCML has been rewritten from the ground up with better code, new features, and better performance. Key changes:

* Multithreading for faster installation
* Support for new BCML Nano Patch mod format
* Can merge new kinds of mod changes, including actor info, game/save data, map units, and individual AAMP files
* Supports any language and region

Fixes such bugs by always starting with a fresh RSTB before merging

The popular new mod [Crafting Project](https://gamebanana.com/craftings/103) has unveiled a handful of issues in BCML do to its more extensive nature than most mods. This new release should offer stable compatibility with Crafting Project and future mods of a similar nature. Changes below:

**Bugfixes**:
* Fixed no hash for `AocMainField.pack`
* Fixed canonical path for files in aoc packs
* Switched all code to use `.tar.lzma` version of MSYT reference pack
* Fixed temp directory cleaning error

**Improvements**:
* Automatically add RSTB entries for new content where possible
* Added support for mod-original MSBT files

Fixed a bug where the GUI would automatically exit whenever a mod failed to extract. Now it refrains from doing so and gives better, more precise error messages.
