0.2.0

This is a big update brought to you mostly be @Kneesnap with some help from @colinator27. It includes a ton of decompiler improvements that make the decompiled code fully compatible with GMS syntax and more readable than ever before. This update is so big that I decided to call it 0.2.0, increasing that number for the first time ever.

Here is the full changelog:

• Make the decompiler output syntax fully GMS compatible - @Kneesnap
• Add support for while(condition), do...while, for and repeat loops - @Kneesnap
• Collapse complex conditions using || and && - @Kneesnap
• Support for "else if" - @Kneesnap
• Support for ternary operator "x ? y : z" - @Kneesnap
• Fix problems with decompiling increments and decrements when return value is used somewhere - @Kneesnap * Fix problems with string quoting in the decompiler and assembler - @Kneesnap
• GMS 2.2.2+ support - @colinator27
• Fix bugs that caused stack variables to desynchronize sometimes and cause decompilation failures - @colinator27
• Fix dup.l 0 decompilation - @colinator27
• Rewrite the sprite import/export code to be less buggy and allow usage from scripts - @Kneesnap
• Allow access from scripts to some more useful namespaces - @Kneesnap
• Allow script access to JSON serialization - @Kneesnap
• Add a progress bar for scripts - @Kneesnap
• Fix incorrect extension filter when importing sounds - @krzys-h

0.1.19

• A lot of work bringing the room editor up to date with GMS2. The preview doesn't work yet, but everything else should - feel free to start datamining the Deltarune rooms! :D
