#2 Several changes...

[Thomas Hansen]

Too lazy to do a diff so I\m just zipping the whole
thing...

* Added support for NAnt solution builds through
opening and modifying the actually project files and
adding reference to the NCover.dll

* Rearanged the XSLT formatting SERIOUSLY since the
original one is really crappy and impossible to read
(tables used extensively)

* Added attribute on "ncoverreport" named
"forceHistoryAdd" which defaults to false but when
added and true it will add up into the history even
though the percentage haven't changed

* Other minor changes...
