After the instalation of erp5_web_renderjs_ui a new skin was introduced.

This is a legacy script, it is not required to keep a script only for a single getUid.

- Move Ticket list to myspace, as it is the most usefull communication channel.
- hosting site is used as back end shop (like a cloud manager ui), so we directly show login page.

Simply drop all the parts which are not used anymore for a very long time. It is not usefull to keep it as reference neither (we can use git for that.)

The direct edition of the Software Instance by the user is unwanted and dangerous, this commit only removes already disabled code.

If user set create_tap to True then specify an interface (tap_gateway_interface) to use as gateway for
guest vm connected to tap interface, slapformat will configure route
to reache each guest from host: "route add -host tap_ip dev slaptapXX",
where tap_ip belong to the same network as the ip on tap_gateway_interface.
slapformat will also create network information for each tap
who will be used to configure network in guest vm.

This is a begining to create cluster of vm which are connected to
each other using tap interface, without bridge.

This commit includes several pure syntax fixing.

This commits aims to fix collision by using 2 diferent portal_skins folders for slapos_jio and erp5_hal_json_style, allowing us let both coexist on production.

Otherwise some prices are displayed with too many numbers after the dot.

Minor optimisations included.
