<Swing Dev> [9] Review Request: 8179596 Update java.desktop to be HTML-5 friendly

[Sergey Bylokhov]

Hello,
Please review the fix for jdk9-dev.
This fix is a part of the effort to make all javadoc in jdk9 be compatible to HTML5.

In the fix the most common issues are fixed.
The issues related to tables will be fixed later, because it is depends from the new html styles which are under review[1].

After the fix the number of errors reported during the build in java.desktop module decreased from 300+ to 110.
