Corrected a problem with an uninitialized entry in ExtCurStyle that

could cause serious errors on systems that do not auto-zero allocated
memory.  Also:  Fixed an error introduced by a recent commit to allocate
character memory for efReadLine() which frees the memory before reading
a .res.ext file, causing a crash when using "ext2spice" with the
"extresist on" option.
