Improve search widget styling (#359)

Slightly improve search widget in several areas, mostly look and feel. Nothing fancy, just light touches here and there.

* СSS:
	* Increase font size (11px → 13px)
	* Use pixels for paddings
	* Always outline search input field on focus
* i18n: use capitalized notation for search text
* Remove empty label
