Styled index.html
Removed outer and inner CSS selectors

They were used for centering blocks. They won't be used anymore because
they interfere with the separation of content and style between HTML and
CSS. They require placing style related information in HTML file.
style.css: Shrinked indents to 2 spaces

From 4 spaces.
search.html: Made the whole LI elements hyperlinks
search.html: Enclosed the list in a div

The div class: "searchResults"

Changed id index to class index in index.html. Propagated the change in
style.css.
Added some style to tables and forms
Specified CZK currency with CSS
Added some CSS elements required by the assignment
