SQL-Statement-1.406_001

Changes for version 1.406_001 - 2015-05-20

Misc
- clean up Makefile.PL, meta-data and requirements
Bug fixes
- Fix SQL function CONV to use limited number of sane character sets for conversion and rely on Math::Base::Convert instead of own code (suggested by Tom Wyant in RT#100551, thanks Tom)
- fix handling of literal identifiers and for every IMPORT rely on literal identifiers to avoid parser errors for column names starting with numbers or similar
- fix capability cache: "$class->can(...)" might return undef and therefore inexistent capabilities are queried to often
- Fix COUNT(DISTINCT col) without GROUP BY clause (patch submitted by Grant Mathews, thanks Grant)
- Fix "parse insert with functions" submitted via GitHub PR#6 by fecundf and RT#96628
- Fix RT#93320: SQL-style comment can not begin inside quotes by Tom Wyant - thanks Tom
Improvements
- reduce blocks and rewrite some inner statements to increase speed of sql command processing
