V 0.1.12

V can finally compile itself on Windows. (https://github.com/vlang/v#mingw-w64)
os module now uses optionals in all functions that return File. Lots of bugs with optionals fixed.
println was optimized. It no longer results in allocations. Now it also works correctly with all integer types.
Lots of vfmt fixes, it will be enabled tomorrow.
New strings module.
Lots of other fixes and improvements, thanks to all the contributors.

V 0.1.11

Windows support via MinGW-w64. Pre-built Windows binary.
File structure has been simplified: all vlib modules were moved to the vlib/ directory, makefile was moved to the root.
One single archive with pre-built binaries for all operating systems.
mut var := val was fixed (previously mut var = val was allowed as well).

Single file programs without fn main now work as expected.
REPL has been fixed: it now supports imports, consts, function definitions, etc.

All C code in the compiler and vlib has been replaced with V.
# syntax for embedding C code has been removed.
Exported functions now need to be marked with pub, all public vlib functions have been updated.
CI has been set up (Travis + Azure). On every commit and PR it is made sure that V can compile itself, all tests pass, and all examples compile.
More tests have been uploaded.
Cleaner bytes to string conversion: tos2(bytes) => string(bytes).
The home page has 3 more examples next to 'hello world' that show the features of the language.
Lots of bugs and issues fixed.
