add reader support for #; #` #' #, and #,@. fix bug in compile-and-load.

Browse source 
* libguile/read.c (flush_ws, scm_read_commented_expression)
  (scm_read_sharp): Add support for commenting out expressions with #;.
  (scm_read_syntax, scm_read_sharp): Add support for #', #`, #, and #,@.

* module/ice-9/boot-9.scm: Remove #' read-hash extension, which actually
  didn't do anything at all. It's been there since 1997, but no Guile
  code I've ever seen uses it, and it conflicts with #'x => (syntax x)
  from modern Scheme.

* module/system/base/compile.scm (compile-and-load): Whoops, fix a number
  of bugs here.
