CEDET (srecode-insert-fcn): Fix use of oref on a class

* lisp/cedet/srecode/insert.el (srecode-insert-fcn): Fix use of oref on
a class.  Reported by Pierre Lorenzon.
(srecode-template-inserter-point): Remove declaration.

CEDET (srecode-create-dictionary): Avoid obsolete object name

C-x 8 shorthands for curved quotes, Euro, etc.

Although C-x 8 lets you insert arbitrary Unicode characters,
it's awkward to use this to insert commonly used symbols such as curved
quotes, the Euro symbol, etc.  This patch adds simpler sequences for
characters commonly found in English text and in basic math.
For example, assuming the Alt key works on your keyboard and iso-transl
is loaded, one can now type "A-[" instead of "A-RET LEFT SIN TAB RET"
to get the character "‘" (U+2018 LEFT SINGLE QUOTATION MARK).
