[pve-devel] [PATCH widget-toolkit] fix: toolkit: make email regex pattern match pve-common

[Stefan Sterz]

`proxmoxMail` used its own regex pattern to validate emails. that
meant certain email addresses were rejected by the front-end that
were accepted by the backend that uses the functionality from
`pve-common`. examples include the following:

- "user at host.test-tld"
- "user- at host.testtld"
- "user at host"

note that there are many many regex patterns that could be used
(e.g.: [1]). im partial to w3c's approach [2], mainly because it's
likely to be widely used, while being fairly simple and compatible
with perl and javascript.
