Protein physicochemical properties calculator GUI: ProtParam based windows and linux GUI executables that output the id, pI, charge, molecular weight and pH of each protein

added from the previous version: smaller executable sizes and new icon for the GUI(so that you can pin it to start or taskbar or create shortcut)

The program has now 3 options for charge calculation:
1. use 1 pH value for all proteins
2. use 1 pH value different for each protein
3. use many pH values each 1 of them for all proteins
