Add GLOB function, other misc fixes

Applied the following changes to aagDBLib

Removed dbA["where columns"] code (duplicate code in dbWhere, contained bugs in dbIn, duplicate code in dbLike)
Fixed bug in dbIn/dbNotIn where "AND"/"OR" concatenation operators were added to the IN clause
Added dbGlob function for case sensitive matching
Added parenthesis level counting, automatically close unmatched parenthesis when performing dbGet
Fixed bug relating to how concatenation operators handled with parenthesis

Also applied those fixes/changes to the new aagRemoteDBLib (done as a separate single commit)

(Thought I had submitted this 8 months ago, but I did the PR against my fork instead of the master... oops)
