[16.01] Backport uwsgi fix from #2836.

Now that newer releases require a library that the mere presence of breaks an older version of Galaxy, I think this will be encountered more during development. It is breaking Planemo's ability to switch between different versions of Galaxy.

[16.01] Backport #3122 #3124 - fix unescaped & in integrated_tool_panel.xml

This should fix #3084.

[16.01] Backport #2869 Fix initial conda version at 4.0.5

This should prevent missing `activate` in <conda_prefix>/bin when
downgrading to 3.19.3. This is what the conda people use in their CI
environment (
[see](https://github.com/conda/conda/blob/master/utils/travis-run-install.sh#L61)
and perhaps why that bug made it into the release in the first place).

[16.01] Allow admin to serialize/deserialize dataset permissions

  ** dataset_manager.permissions.manage
- Update bad test

The power was inside you all along.

And updates tests.

[16.01] UI, history: replace copy dialog on grid refresh

Fixes #2624

init_grid is called from update_grid to rebuild the grid. This patches
that call to replace the copy links with the dialog.

Note:
- related to #1303 which was an effort to make a single code path
for copying histories.
- Uses monkey patching to keep from porting build artifacts.

[16.01] Fix move_directory_files tool dependency action when destination is not empty

Historically this action moves the contents of the source directory to the
destination directory. Commit d38936bd
broke the install when e.g. the destination is $INSTALL_DIR, which is
created by Galaxy and is not empty (contains INSTALLATION.log after first
action).
