[Plugin: PdAlex Glossary] addslashes creates broken title link

I like this glossary plugin. However there is a significant bug. A backslash is being added before characters that need to be quoted in the database, such as single quote (‘), double quote (“), backslash (\). This is harmless if the backslash is in the entry content, however if the backslash is in the entry title it breaks the link to that entry.
