Sed inline parameter error on macOS

[jido]

The makefile uses sed -i, which requires an extension parameter on macOS and on FreeBSD.

Error when running make all:

Generating the parser, this may take some time...
jison --outfile TeXZilla-web.js --module-type js --parser-type lalr TeXZilla.jison TeXZilla.jisonlex
sed -i "s|\\\\b)/|)/|g" TeXZilla-web.js # jison issue 204
sed: 1: "TeXZilla-web.js
": invalid command code T
make: *** [TeXZilla-web.js] Error 1

To correct that, edit the makefile to add "" after -i on each line where it is used:

sed -i "" "s|\\\\b)/|)/|g" $@ # jison issue 204
