Issue with special characters

[GigiusB]

Unfortunately complicated passwords may contain special charcaters that need escaping.

Most of all if the password contains ":" then there regex will fail.

I suggest changing it from PATTERN = re.compile(r'^(.*):(.*):(.*):(.*):(.*)$', re.MULTILINE)
to: PATTERN = re.compile(r'^([^:\n]*):([^:\n]*):([^:\n]*):([^:\n]*):([^\n]*)$', re.MULTILINE)

However in addition to ":" and "" I also found "," that will need escaping.

So I'd suggest to add the following to the _sanitize_str method...
.replace(r',', ',').replace('\\', '\')

Thanks, will look to make these changes when I can next jump in the code. Working on the next version is bubbling up in my list.
