Bump hslua version to 0.9.5

This version fixes a bug that made it difficult to handle failures while
getting lists or a Map from Lua. A bug in pandoc, which made it
necessary to always pass a tag when using MetaList or MetaBlock, is
fixed as a result. Using the pandoc module's constructor functions for
these values is now optional (if still recommended).
