#13 Assume rz.exe/sz.exe in program-dir of putty.exe

[Joachim Otahal]

LePutty should assume that rz.exe and sz.exe are at the same place where putty.exe is located.
Even if the options say that it is somewhere else, fall back to check the program directoey if the rz.exe and sz.exe were not found at the configured places.

kind regards,

Joachim
