version 1.2

When two builds attempt to archive the same output at the project level at the same time, the following output can be seen:

[htmlpublisher] Archiving HTML reports...
[htmlpublisher] Archiving at PROJECT level <source> to <destination>
FATAL: HTML Publisher failure
java.io.IOException: Unable to delete <destination>

This is likely due to the setting of "BuildStepMonitor.NONE" meaning that each build does not wait for the previous one to complete before processing it's post-build steps. I believe this is correct when archiving is at the BUILD level as there is no clash of file access but for PROJECT level this should be changed to BuildStepMonitor.BUILD (if I have understood the javadoc's correctly)
