wx.metadata: several issues in syntax

[sbl]

wx.metadata has a couple of issues mostly due to changes in underlying libraries, I guess. The attached diffs fix some of them, but remaining issues amongst others require wxGUI programming skills, which I do not have unfortunately.

After changes applied editing metadata still throws:

Traceback (most recent call last):
  File "/home/stefan/.grass7/addons/scri
pts/g.gui.metadata", line 506, in onEdit
    ok = self.editMapMetadata()
