chibi-scheme0.5 release

Lispor

Chibi-Scheme is a very small library intended for use as an extension and scripting language in C programs. In addition to support for lightweight VM-based threads, each VM itself runs in an isolated heap allowing multiple VMs to run simultaneously in different OS threads. The default language is R7RS Scheme, including first-class continuations and low-and-high-level hygienic macros.

新特性：

• draft R7RS "small" support
• image file support for fast loading
• support for complex numbers and exact ratios
• {brace} syntax for user-defined type literals
• better OOM handling and memory tests (now valgrind safe)
