Code page 65001

[axben]

@Araq: Since v0.15, whenever I run "nim.exe" (or a program compiled with the 
new compiler) my console's copde page is changed from 1252 (Windows Latin-1) to 
65001 (UTF-8), which is - let's say - a litte counter-productive in my 
environment. So, please have the compiler (and compiled programs) respect the 
current console's code page!
