[release] Jelix 1.2.7 is available

[Laurent]

A new version is available in the download area, for the 1.2.x branch.
You can update your jelix 1.2.x applications without modifications.

It fixes a issue during the check of some data types in jForms.
Whitespace are now ignored (except for simple strings).

It fixes also a serious bug: an infinite loop could be started when some
errors were triggered.

All details of changes here.
