Iniparser: added file with changes, and changed all error messages, prefixed with "SNOOPY "
Changed --with-config-file=PATH to --enable-config-file: old way was very confusing as it had two ways of specifying path to configuration file
Also, install config file BEFORE library is installed, to avoid short timeframe where library is searching fir non-existing config file.
Version bump to 2.0.1
