TC7rc4 - Change Attributes, group box Change plugin attribut

[white]

Suggestion for the Change Attributes dialog (menu Files/Change Attributes).

As suggested by petermad here create a group box for the options concerning changing plugin attributes values (see petermad's screen shot). This way the dialog becomes much more clear. Especially it is more clear that the option F2 Load/save settings only applies to the settings concerning changing plugin attributes values.

Furthermore, such a group box makes it clear that the button: "Load from file under cursor" applies to all attributes, not only to plugin attributes.
