[ADQL] Fix table copy bug: the catalog and schema names where not copied or not interpreted when they were prefixing the new table name. WARNING: The copy function of a DBTable has a slightly different behaviour than before.

[ADQL] Fix SQL translation of NOT BETWEEN (before it was translated by just BETWEEN ; NOT was forgotten)

[ADQL] Fix SQL translation of operations' alias: now, the alias is always surrounded by double quotes (so a sum between two numbers won't have the default alias +, but it will have +)

[TAP] Remake TAPFactory into an abstract class + let limit the number of jobs (async and sync) by allowing the TAPFactory to communicate with a connection pool

[TAP,ADQL] Improve and remake a part of the database connection. Missing javadoc has been added when missing in the modified tables.

[TAP] Remove all generic types + Delete specific (for ResultSet) output formatters + Modify the main output formatter

ADQL: Provide the position of any column reference (column in ORDER and GROUP BY) when returning a ParseException

ADQL: Fix big bug: no parenthesis in the SQL translation for ADQL constraints with parenthesis ( ex: A AND (B OR C)) )

1/ let the function ROUND having 2 parameters
2/ wrap Operations (WrappedOperand) with brackets when there are brackets in the ADQL query

ADQL: Correct version number for all modified ADQL related classes since the official v1.1 release. Now, version number after any modification in ADQL is v1.2.

ADQL: Fix an ADQL bug (raised by Dave Morris) in the management of subqueries: before, it was impossible to use (in a clause different from the FROM) columns of a father query inside a subquery.

Becareful with the function addMatch(ADQLObject, ADQLIterator): the iterator may be null if the match to add is the root search object itself!
No modification needed in SimpleReplaceHandler: Null test already done :-) !

ADQL: Completely change/improve Joins management, and particularly NATURAL JOIN and USING JOIN. Now, every joined columns are represented by a DBCommonColumn instance which has a given table coverage.
Before, there was a problem while using at least 3 or 4 NATURAL JOINs. Bug raised by Menelaos Perdikeas (ESAC).

ADQL: Fix ArrayIndexOutOfBoundsException while initializing a DefaultUDF (User Defined Function) object with several parameters.
