This PR aims to cleanup the currently quite messy DependencyControl situation in this repo. This includes the following changes:

• Merges upstream changes from unanimated/luaegisub
• Merges https://github.com/unanimated/luaegisub/pull/15
• Fixes script_namespace of FadeWorkS and Colourise which caused the macros to show up twice in DependencyControl interfaces after installing
• Merges https://github.com/TypesettingTools/unanimated-Aegisub-Scripts/pull/1, which will prevent some invalid hash issues. Currently the feed from this repo is in DependencyControl, but the files get downloaded from unanimated/luaegisub. This currently causes a hash mismatch when installing Relocator.
• Remove UTF-8 BOM in depctrl feed (invalid JSON per specification)
• Bump minor version of all macros and update hashes in depctrl feed
