kprintf

It is just my variant of printf.

kprint

I don't really like printf function (and its variants), so i made safer and more convinient replacement.

function	returns	arguments
kprint	void/throw	kprint_format, void, kprint_format, void...
ksprint	Maybe<char*>	kprint_format, void, kprint_format, void...
kfprint	Maybe	FILE, kprint_format, void, kprint_format, void*...

format construction:
```
kprint_format fmt= kprint_fgColor | kprint_bgColor | kprint_fdataFmt | flags | ktid;
```
more about kprint_format
- fgColor and bgColor can be set to change console output color
- you should set dataFormat for int/uint/float/char* arguments and ktid for other types
- flags can be set to modify TypeDescriptor.toString() behavior
- don't forget to set TypeDescriptor.toString when registering type, or kprint will crash
using base type arguments:
you can just put them into a function
```
kprint(kprint_fmtHex | kprint_fmtUppercase | kprint_fmtWithPrefix, 255);
```
output: 0xFF

using other registered types:
should be sent as pointers

Maybe m=MaybeNull;
kprint(kprint_fgBlue | kprint_fmtString, "Maybe: ", kprint_fgGreen | ktid_MaybePtr, &m);

output: Maybe: {value={0, ktid_Null}}
