ae.r now generated using def2write_r like cse?.r
fix_c.r called at ese2rdae stage so that pow gets fixed in ae.r.

These changes produce the desired result (optimised algebraic equations) but
have highlighted a problem; when optimisation fails, Reduce does not write
a result. For complicated systems, this can lead to missing assignments in
the resultant code. file: [4bd66676aa] check-in: [ea9834becc] user: geraint@users.sourceforge.net, branch: origin/optimise-algebraic-equations, size: 11101 [annotate] [blame] [check-ins using] [diff]
