Fix exception handling and LNK info parsing

[Matmaus]

The PR solves issues found in #15 :

• catch more exceptions, and use warnings instead
• replace unknown characters in UTF-16
• treat 0 time as a valid value (it means a file was created in an application and never ever opened)
• always return at least Target name when there is any problem
• fix parsing and output position of LNK info (common_path_suffix, local_base_path, ...)
• disable MyComputer target (it is not implemented yet)
• fix printing of net_name, device_name, and local_base_path
