Better version handling in fcompiler

 * Remove FCompiler.get_version_cmd, FCompiler.get_flags_version,
   FCompiler.get_linker_so_cmd, and FCompiler.get_linker_exe_cmd;
   subclasses should do this in FCompiler.update_executables()
 * FCompiler attributes .compiler_f77, .version_cmd, etc., are now
   properties that read from the .executables dictionary.
 * Update intel.py and absoft.py for above
 * Add extra asserts for defensive programming. Most of our problems
   here seem to come from bad values being generated, and the error not
   being caught until later.
     * must call FCompiler.customize() before FCompiler.get_version();
       command/build_ext.py and command/config.py updated
     * verify that commands make sense earlier -- must be None or
       lists of strings

Also,
 * add IA-32 as another pattern to search for in 32-bit Intel
   compiler version.
 * minor formatting
 * add debugging helpers to environment.py:EnvironmentConfig class
