* [msbuild] Added a PropertyListEditor task which works like PlistBuddy
This is a convenience Task for customers and isn't currently used
by the core MSBuild targets.
* [msbuild] The PropertyListEditor task does not need a SessionId property
* [msbuild] Added support for non-container root plist elements
* [msbuild] Catch & log exceptions loading plist document
This makes us only put packages in one directory (saves disk space and time),
and it also makes project files in multiple solutions work properly
(mtouch.csproj is in tests/tests.sln and tests/mtouch/mtouch.sln).
For whatever reason, VS added it even if the package version is
0.9.5, but VS happily finds it and everything builds fine but
it breaks on xbuild/mono/mac??
* [msbuild] Remove unnecessary duplicate implementation of Move
Our implementation of the Move task was a partial copy of what
the MSBuild Move task does: https://github.com/Microsoft/msbuild/blob/master/src/XMakeTasks/Move.cs
Remove the unnecessary code, make it inherit the base implementation
like we do for the other MSBuild-overriden tasks, and place it in a
corresponding MsBuildTasks folder to denote this (again, like we do
in iOS.Tasks).
Removing this (unnecessary IMO) custom implementation of Move
ensures that when we switch to MSBuild, we can leverage improvements
and fixes on the task automatically.
* [msbuild] Move all the common MSBuild overriden tasks to MacDev
These tasks previously existed in iOS.Tasks, and Mac.Tasks. Since
they are reused across iOS and XM targets, move them to the common
MacDev project and update the targets accordingly.
Like the Copy/Delete/MakeDir/RemoveDir/Touch tasks, we need to override
this one so we can allow customer targets to also execute Mac tools
remotely when building from Windows, bringing parity to the build
customizations allowed on XS/xbuild since they build locally and Exec
"just works" there of course.
