Update of /home/cvs/GiNaC/ginac

Modified Files:
	inifcns.cpp inifcns_gamma.cpp inifcns_trans.cpp pseries.cpp 
Log Message:
- remove some explicit accesses to ex::bp by replacing with ex_to<>().
- log_series(): check if the argument expands simply to Order(x^foo) and
  if so expand somewhat further in order not to produce rubbish like
  log(Order(x)^(-1)... and such.
