Version Control With Subversion Source

Ticket #20 (cf. http://www.svnbook.de/ticket/20 on behalf of Wolf Peuker).

Compress the HTML stylesheet a bit by adopting a different formatting
style.

* src/en/book/styles.css
White-space changes only, save collapsing some similar styles into
one block and setting "border-collapse: collapse;" for 'table' tags.

Fix the double-admonishment-graphic problem.

* src/en/book/styles.css
Newer versions of the XSL stylesheets are a) picking up the
admonishment images by name mathing now, and b) formatting
admonishments using a two-column table (with the graphic occupying
the left column, and the text the right. So we can lose some of
our HTML stylesheet stuff now. (I wish I knew a way of doing
this kind of stuff optionally based on versions of tools and
XSL stylesheets and such. But I don't.)

* src/en/book/ch02-basic-usage.xml
Follow-up to r3674, continuing what 'songdongsheng' begun in the
area of cleaning up improper uses of the <computeroutput> tag.
