Fixing issues in rockspec

Fixing issues in the rockspec of the previous release and adding latest commits.

Requiring LPegLabel 1.6.0

LPegLabel is returning the subject position (number) related to the error instead of the subject itself (string) where the failure occurred, as it used to be until LPegLabel 1.4.0. This version fixes the code to use the new LPegLabel approach and sets the rockspec to avoid installing previous versions of LPegLabel that would regress the fix. LPegLabel 1.5.0 is being skipped because it has a head fail optimization bug that is fixed in LPegLabel 1.6.0.

Moving from LPeg to LPegLabel

This release uses LPegLabel to give better error messages while parsing Lua code.

Thanks to @undecidabot and @sqmedeiros for their work on this release.
