Problem with file names' managment in long path

[CyrilleB79]

6pad++ version alpha 10 does not manage long file path correctly.
The following behaviour may occur:

• when trying to open a file foo.txt from Windows Explorer, the window title indicates a modified name (e.g. foo.txS)
• when trying to save this file after modifications, a new toto.txS file is created and toto.txt is not updated with the modifications.
• 6pad++ opens the file foo.txt with a wrong name (e.g. foo.txS) ; when the file is then saved, a new file foo.txS is created instead of updating foo.txt.
• 6pad++ cannot be opened anymore, probably due to wrong file path/names in 6pad++.ini

Steps to reproduce the issue:
1- Create the file D:\Test6pad\Test6pad\Test6pad\Test6pad\Test6pad\Test6pad\Test6pad\Test6pad\tata.txt
2- Delete (after saving it) the file 6pad++.ini
3- From Windows Explorer, open tata.txt in 6pad++
4- Close 6pad++
5- From Windows Explorer, open 6pad++.exe
7- Close 6pad++
8- From Windows Explorer, open tata.txt in 6pad++
9- Close 6pad++
10- From Windows Explorer, open 6pad++.exe
-> 6pad++ does not open
It is due to the file tata.txS written in 6pad++.ini
