monitor fix.

Added autocompletion to build after other textbox, and textboxes can now use autocompletion without needing a true field via the autoCompleteField attribute.

JNLP is implementation detail. Java Web Start is a better known term, although this can be still improved.

on IE8, <A> element always gets empty string as name, not null. Empty name is not valid any way, so detect that accordingly.

in IE, innerHTML of TABLE is not modifiable (See http://support.microsoft.com/kb/239832), so this doesn't work. Looking at the similar code in the latest prototype.js, a work around is to create the full TABLE HTML fragment and inserting it to DIV.

in Firefox 3.6 on amd64 Ubuntu that I tested, setting innerHTML of TBODY to "<tr>...</tr>" doesn't just add a TR, and Firefox tries to fix it to something broken. But setting innerHTML of a TABLE to "<tr>...</tr>" works as expected.

that results in missing tail bits when the master is heavily loaded.
