#74 Files without extension

[tkacz]

Version 0.8.2.
When I have files without extension, i.e. "xyx", program can change its name to "xyz." [and not look for a criteria od changing names]. But file "xyz" its thet some with "xyz.", then Program report error, and say: "I can rename this file in folder "t_e_m_p_". When I click YES, Program move ALL files wrom current dirrectory to "t_e_m_p", and still dont look to criteria.
