Update AL-5-exp.enc (add 3 glyphs, rename 6)

Also added explicit .notdef. updated langauge listing in comments.
Later revision to AL-5 added the inherited AL-3 and AL-4 changes.
AL-4 added the Indian rupee (uni20B9)
AL-3 added the Russian ruble (uni20BD) and Turkish lira (uni20BA) symbols, renamed the Scedilla/scedilla uni015E/uni015F, and Scommaaccent/scommaaccent to uni0218/uni0219, 
and disambiguated the Tcedilla/tcedilla as uni0162, uni0163 (no longer naming them Tcommaaccent/tcommaaccent in addition to the appropriate uni-named glyphs).
