Default adresse layout update

As many countries use mobile phones in an extensive way, it should be
useful to update the default address layout
Default tinySetup configuration update

The default tynyMCE configuration for back-office uses only two lines of
buttons, like for CMS pages. But the product admin controller uses the
full version.
I think this complete version should be enabled on CMS pages (and on all
the editor occurences) : the merchant must be able to customize HTML as
he wants.
WYSIWYG editor CSS update

The text in the tinyMCE editor is stucked to left side (since at least
Prestashop 1.4) : it should be visually a good thing to add some space
Excel CSV compatibility

The CSV files generated by Prestashop need to have a BOM at the
beginning. If not, Excel throws an error about unrecognized format.

The HTML entites must be also converted : "&eacute;" (for example) is
not compatible with the usage of ";" as value separator
Import time reduction

The cleanPositions method generates as many queries as you have
ps_feature entries.
So, repeat it by hundreds of products and your import should be very
long.

The above query avoids it (the import time is about 5 min for 900
products instead of more than 20 min).
Typo

I typed "SELECTT" instead of SELECT
