v0.1.0

Added:
 * Dynamic Arrays `[...]Type`
 * Dynamic Maps   `map[Key]Value`
 * Dynamic array and map literals
 * Custom struct alignemnt `struct #align 8 { bar: i8 }`
 * Allow `_` in numbers
 * Variadic `append`
 * fmt.sprint*
 * Entities prefixes with an underscore do not get exported on imports
 * Overloaded `free` for pointers, slices, strings, dynamic arrays, and dynamic maps
 * enum types have an implict `names` field, a []string of all the names in that enum

Removed:
 * Maybe/option types
 * immutable variables
 * Remove `type` keyword and other "reserved" keywords
 * `compile_assert` and `assert`return the value of the condition for semantic reasons

Changed:
 * thread_local -> #thread_local
 * #include -> #load
 * Files only get checked if they are actually used
 * match x in y {} // For type match statements
 * Version numbering now starts from 0.1.0 and uses the convention:
 	- major.minor.patch

Fixes:
 * Many fmt.* fixes

To come very Soon™:
 * Linux and OS X builds (unofficial ones do exist already)
