#25 imprecise ioPage editing

[idleberg]

whenever i move my items around in the editor and press
"save", hm nis tends to adjust the positions of some
items. this can be annoying (i always have to edit my
io-files in notepad afterwards). please note, that snap
to grid is disabled!

the io editor is also imprecise when it comes to
textlabels. though it always adjusts the width of my
field depending on the length of my word, it happens
quite often, that some pixels on the right are cut (in
the compiled installer!).
