#90 reading password from file is limited to 16byte passwords

[Duncan Idaho]

Reading passwords from file, via -f switch, is limited to 16byte passwords only. This is because of hard-coded password length in ipmi_password_file_read(char * filename) in 'lib/ipmi_main.c'.

Noteworthy lines:
~~~ SNIP
char * pass = NULL;
pass = malloc(16);

if (fgets(pass, 16, fp) == NULL) {
~~~ SNIP

Suggested fix? I'm sure there can be more than one, but how about to allocate and read 20bytes instead of just 16?
