1.4.0

Major changes

• A new web UI, with a menu to select flags. It shows side-by-side how the shader with minified, with hypertext links to better track variables after renaming.
• Better support for interface blocks (#237).
• kkpView symbol generation for integration in kkpview (usable with kkrunchy and crinkler)
• Better minification through variable reuse, more inlining, more variable shadowing, and more.
• Better tracking of side-effects in the code, which leads to better and safer optimizations.
• Multithreading to make Shader Minifier faster when minifying multiple files together.
• A .NET API, for example if you want to plug the minifier in your C# tool.
• And a bunch of bug fixes!
