This setting originally only worked for the Summary page, but since that
page was written, other pages have offered graphing.  This setting will
now disable Google Chart requests on the Dashboard, Activity, and
Summary pages.

This is related to issue-310.

The graph is generated server-side and therefore requires that the
commit table row height be fixed and match the row height of the
servlet.  There will be layout misalignment if remotes refs are
displayed.  Perhaps this can be improved in the future.

NPE fix in default branch determination & NPE fix when commit cache contains removed repo

This is a normal condition that complicates debugging, i.e.
when catching all NPE's.

Add the commons-io library explicitly to the depencencies.
It was already present as a transitive dependency but is now used in code.
Using the version 2.2 as that got so far already packaged in ext.

Implement adjusting file and directory permissions for shared
repositories in JGitUtils.

Implement the methods getFilemode and setFilemode
in JnaUtils. Not using the libc names as we don't
necessarily use JNA and because it is not necessarily
a one to one mapping.
