Fix application version check

The `NPPM_GETNPPVERSION` API returns a single DWORD that breaks down
to a high and low value (*). The low value is parsed from a version
string that is "descriptive" rather than semantic (**)

Most often there are 3 digits, e.g. "8.33". But with every "minor
version" bump, it's reduced to only 2 digits, e.g. "8.4"
