Style search input

[DrDrij]

• Hides the overlapping close/clear icon on webkit browsers.
• Animate the opening of the search input field.
• Simplify JS.

If this works well, last step to allow clicking magnify to submit form (and clicking away from search to close input field).

@DrDrij it looks like you have created this from another branch?

@mmcky Shall I reapply the changes to a new branch? I used this one as it was the branch Aakash added search with.

@DrDrij the search PR has been merged and for some reason this has merge conflicts so maybe you branched off some intermediate state? Not sure. I think the easiest is to setup a new branch of the latest master 👍
