don't format numeric values when used as value attribute of `input type="number"`

fix for GRAILS-8946
Use `step="any"` on non-integer numeric inputs or those with a scale >= 7

This fixes 2 things:

1. If a floating point numeric property has no `scale` constraint then the scaffolded input would have no `step` attribute meaning Webkit browsers prevent input of decimal data.

2. If the field has a `scale` constraint >= 7 then the `step` attribute was being set to an invalid value.

Fixes GRAILS-8463
Fix for GRAILS-8433 using H2 database: increase H2 lock timeout from 1000 ms to 10000 ms
Fix for GRAILS-8433: disable query cache when lock=true; make it possible to disable caching for a query
related to GRAILS-8049; more consistence to caching all queries when "grails.hibernate.cache.queries = true"
Fix for GRAILS-8988 GORM autoTimestamp not working due to org.hibernate.PropertyValueException
Move nullability checking to a PreInsertEventListener so that autoTimestamping happens before nullability check.
Fix for GRAILS-8393 (javac: target release 1.6 conflicts with default source release 1.7)
Improved fix for GRAILS-8988: make the previous fix thread safe (register pre-insert event listener at startup)
More fixes for GRAILS-8988 , support for inserts that use primary key that is given/generated by a sequence (=PostgreSql)
performSaveOrReplicate method has been changed to never delay inserts so that PreInsertEventListeners can modify the entity field values before inserting.

Merge branch '2.0.x' of github.com:grails/grails-core into 2.0.x

GRAILS-9040 - fix flash.now

flash.getNow() was working but flash.now was not.
