rephrase statements about check-in procedure

I avoid using the term 'registration' for both ticket buying and
on-site identity confirmation. I currently put the latter as 'check in'
but I am not sure whether reg team will agree on this decision.

Also list style on mutliple id verification is changed, to enumerated
list is a bit confusing. Work on #45, #50
use html structure same as eng ver; modify content

some statements are rephrased, like 「註冊」與「報到」. Also Chinese punctuations are all modified to full width characters.

For other changes would be most likely my preference. Any comments are
welcomed :) Close #45 and close #50 as well.
