url portion after the last dot ignored

[helder-jaspion]

HTTrack generates html files named just until the last dot.

Example: .../deputados-querem-cortar-repasses-1.884291 becomes .../deputados-querem-cortar-repasses-1.html

but should be .../deputados-querem-cortar-repasses-1.884291.html

The combination of changing %n to %N (filename including extension) in the custom path spec, and the undocumented -%t flag (which keeps httrack from mangling filenames with dots), and the fix to #55, enables httrack to successfully output HTML files with multiple dots.
