Improved Profile-link Commands

[StraysWonderland]

Minor changes to the profile-commands that display links to girhib,linkedin etc. in the header:

• text displayed by email, linkedIn and github command is now a clickable hyperlink
• linkedIn and GIthub command now only have to display name of the actual profile, not entire url ( 'myprofile' will be displayed instead of 'www.linkedin.com/in/myprofile')
• added two new commands: googlescholar and xing

Thanks for the contributions. However as mentioned in #4 , I've decided against providing further explicit commands for services/platforms because there are so. many. worldwide, and I'm sure more will be born everyday!

For wrapping the links in \href: note that things will break if you have e.g. underscores as in \email{hello_world@example.com}, unless you use a \detokenize for the second parameter of \href. For abbreviating the links: personally I would only make these an option instead of mandatorily shortening them all, because some places still require paper CVs so a more complete URL might be better. These were why I did not make the profile icons clickable at the beginning. Perhaps the time has come to implement options for them.

Yes I see and agree. Did not think of that. I have closed the PR for now. Maybe ill work on implementing optional commands for abbreviated versions of the allready included service commands in the future
