Add intelligent URI paste support

[gaben]

When copying information from websites, the email and phone number values often contain Uniform Resource Identifier (​URI) scheme prefix.

Examples are:

• mailto:
• tel:

(Full list available on the IANA website ​https://www.iana.org/assignments/uri-schemes/uri-schemes.xhtml)

Current procedure

Pasting these values to JOSM involves manually deleting the prefixes and changing tag types.

Ideal procedure

JOSM would recognize the tags and automatically change the tag type according to URI.

Note: there is the increasingly popular contact: prefix which should be considered when adding the tag type.

Mmh, often context of webpages are not allowed to add, due to license issues.

It's up to the user ¯\_(ツ)_/¯

Note to myself: the TextTagParser class has the needed parts.

At least in Firefox you do not have to manually delete the prefixes.

When you right-click such a link there are very handy "copy phone number" and "copy email address" options.
