Add options to disassembler (nis)

[Anz]

the current use of nis looks like: "nis "
whichs show the header, symbol and text segment

add options, so that only the information are which are wanted, like: "nis "
-i show header
-s show symbol table
-t show text segment

the options can be combined like: "nis -is " which shows the header and symbol table

[Anz]

current ouput:

header segment:
magic number        = 0xAFFEAFFE
container version   = 1
content version     = 1
symbol segment size = 25 Bytes
data segment size   = 4 Bytes
text segment size   = 115 Bytes

symbol segment:
0x00000000 = "main"
0x00000028 = "min"
0x0000004B = "max"

text segment:
main:
        arg
        arg
        sync
        arg
        arg
        cmp
        ret
        ret
min:
        arg
        arg
        sync
        arg
        cmp
        ret
        ret
max:
        arg
        arg
        sync
        arg
        cmp
        ret
        ret
        ret

I added the basic function (header, symbol and text) and commited it. there are some bugs with backtrace and memory map, i'll fix that tomorrow!

issue still pending...

I fixed and optimized some 'featurs' and sill working on a parser function.

thx, would also be nice if a warning is shown on a wrong argument

btw use spaces instead of tabs (4 space = 1 tab)
