In Eeschema, texts are expected to have the same size X and size Y.
So we cannot set 2 different values for X and Y pin size:
- only size X is saved in file
- 2 different values for X and Y create bad look for pin + associated graphic symbol
Allowing separte values need a file format change *and* a code change.
They're now used for bus definition control characters.
Also fixes the sheet pin edit dialog to correctly escape/unescape
netnames.

Currently, if a old label already containing a '/' (or a space) is edited, it is accepted,
but no new not allowed char can be added to the label.
(Previously, a sheet pin label was not filtered)
File "rules" has instructional text as comments near top.
2) Convert all text files in repo to LF line ending form.
Any checkout done with "rules" in play will convert the working
tree to native line ending, while keeping repo as LF line ending.
