* remove IT_PIPE duplicate and add IT_GRAD
IT_PIPE was declared 2 times, ones as ° and once as |. I changed the first declaration and called it IT_GRAD. I even fixed the definition because the ° in Italian is obtained with LSFT(IT_AACC)
* rename IT_GRAD to IT_DEGR
* add missing plus_and_minus
* fix missing IT_ACUT definition
* change KC_LALT(KC_LSFT to LALT(LSFT
* Fix alignment

* edited to be easier to compare to _ansi.h
* remove keymap_italian_osx_iso.h and rename with edits keymap_italian_osx_ansi.h to keymap_italian_osx.h
I found out there were no difference at all
* fix missing #endif
* rename quantum/keymap_extras/keymap_italian_osx.h to quantum/keymap_extras/keymap_italian_ansi.h
Now this file is a clone of the keymap_italian.h that appears to be working only for ISO keyboards. It also contains a few improvements for IT_PIPE (defined two times) and IT_ACUT (missing definition). Additionally it redefines LCBR and RCBR to LSFT(IT_LBRC) and LSFT(IT_RBRC)
