Add some optimizations

In this version i have added some optimizations:

 1-  Change  Many to many relation style in list view to a list.
 2- Formatting error messages to be more significant (add custom style file).
 3-  Escape HTML in view list  for a Textarea field with WYSIWYG edito (for example ckeditor).
 4- Avoid Chosen.js conflict in case we have an options select with value "Select". (conflict with "Select" placeholder value)
