bugfixes around display of permanentURIs

[jessopb]

previous behavior:

• AssetInfo PermanentURLs for anonymous publishes was broken.
• Edit claim message "Editing lbry:// had a malformed url.

new behavior:

• buildURI has been renamed to createPermanentURI to be consistent with lbrynet output.
• buildURI has been modified to return proper strings for permanent URIs for both anonymous and channeled claims.
• PublishTools message "editing lbry://abcd" now displays a link text that actually works.
• AssetInfo displays and uses proper permanent URIs for both anonymous and channeled claims.
• @clientutils alias was added to remove confusion about ../../../../../../utils.
