Changes in decimal unsigned columns not detected

[ccerrillo]

Modified regexp to accept unsigned decimal columns

Before the changes on decimal unsigned columns were not detected.

Test case:

FROM:

CREATE TABLE `test2` (
  `id` int(10) NOT NULL AUTO_INCREMENT,
  `fk` int(10) NULL,
  `val` decimal(11,3) unsigned NOT NULL,
  `texto` char(60) NOT NULL DEFAULT 'default',
  `datade` timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP,
  `new_field` int(10) NULL,
  PRIMARY KEY (`id`,`new_field`),
  KEY `FK__test1` (`fk`,`texto`),
  UNIQUE KEY `FK__test1` (`datade`),
  CONSTRAINT `FK__test3` FOREIGN KEY (`id`) REFERENCES `test` (`test1`)
  CONSTRAINT `FK__test3` FOREIGN KEY (`fk`) REFERENCES `test3` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8 ROW_FORMAT=COMPRESSED KEY_BLOCK_SIZE=4 COMMENT='test1';

TO:

CREATE TABLE `test2` (
  `id` int(10) NOT NULL AUTO_INCREMENT,
  `fk` int(10) NULL,
  `texto` char(60) NOT NULL DEFAULT 'default',
  `datade` timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP,
  `new_field` int(10) NULL,
  PRIMARY KEY (`id`,`new_field`),
