#168 Some fixes to Single Bundle View
Nicer dashboard resize handles
Resizing dashboard items actually gets saved now
add a bit more UI polish to let the user know when we're trying to download source artifacts and if we fail to find them we let the user know
fixed compile error
first spike of a fix for #138 so that we have a hawtio-default.war which includes insight-log4j for use in web containers; we still need the blueprint Servlet ContextListener so that we can automatically boot up hawtio-git / insight-log4j etc ideally
add a hand crafted bootstrap until a generic blueprint servlet context listener comes along for #138 so that we can initialise the logger mbean
added a little bit of logging so its more obvious that the Log mbean is actually working ;) for #138
use the latest insight-log4j so that exception stack traces get proper maven coordinates so we get nice links to source code
fixes #129
updated links to next milestone
added ignore
fixes #179 so that Hawtio can be deployed with a different context root / war name than hawtio
Merge pull request #180 from astefanutti/fix179

fixes #179 so that Hawtio can be deployed with a different context root / war name than hawtio
added better error reporting
report exception stack traces (we maybe should make them collapseable)
trimmed the dependencies a little to make the WAR a little smaller
