#1 Some simple changes in qt comsams

[sindolfo]

I'm using comsams with SGH-E700 and SGH-D500 and it is really a very useful tool.

I have some simple considerations for the first release of qt comsams:

- When listing the file system files, the program should list all directories prior to the files.

- The user should be able to create a new directory in its computer file system.

- The user should be able to select a group of files to transfer (currently only one file can be selected and transmitted).

- The program should remember the last used device and fill the device textbox in the startup.

Congratulation, comsams is a great work.
