Inconsistency in how autonomous system names are written in the search page

[rayasharbain]

In most places where the autonomous system name is mentioned, it's written as follows "ASxxxx" with no space between the letters "AS" and the numbers that follow. On the search page however, in the search results, the AS number is written with a space between the letters and the numbers.

Minor issue really, and only noticed it when I was copy pasting ASNs. Not sure what's the correct format is!

Another thing we might want to do is automatically strip the whitespace between "AS" and "XXX" when it's entered into the search filter.
