Added JSON escape \/ into /
Bugfix. Fixed warnings about const char*
Bugfix. Segmentation fault on strlen(\0)
GCC feedback
warning: implicit declaration of function 'bzero'
warning: implicit declaration of function 'getpass'
warning: implicit declaration of function 'strlen'

It seems there is a difference between string.h and stringS.h, XCode
does not worry about it.
Added compile instructions on Ubuntu
Added env_getpass because getpass is obsolete in POSIX
(getpass keeps creating implicit declaration messages on GNU/Linux)
so yes, replaced that with my own code (I feel so dirty!)

Also moved free username+password from api to main, the
const char should have pointed it to me in the past..
env.c
Changed env_homedir from const to char, caller is responsible for cleanup
More strict programming, using bzero
Removed const char* const in favor of const char* for functions
Bugfix. getline returns read string including \n
So set to NULL to fix this
Fixed all strict warnings introduced by Tomarus his WARNINGS-flag in the GCC makefile
Updated makefile to use right filename aci and changed standard from ISO C99 to GNU99
Linux seems like a more strict environment on leaking data, fixed some bugs:
Writing (and then freeing) not allocated memory in main_credential_cache
Removed unused _cookiejar
Seems like we are not allowed to free a temp file
Update README.md

Dashed const
Added markup to Bash-commands
