- The method to minify jflow's sources to jflow.min.js
(https://github.com/mishoo/UglifyJS2) was to advanced, and generated
errors in the code. We went back below the version 3, to avoid the
script being broken when minified.

- The JQuery request 'get_user_files' was bugged because it was trying
to reach ng6-test without the port '8080'.

issue #171

I removed a useless "parseInt()".

issue #170

Every AJAX response is now going to be converted to INT before
evaluation.

issue #170

'add_user' and 'delete_purge_data'.

The code returned in AJAX is now evaluated as an INT instead of STRING.

issue#170

The ajax return codes (0,1,2 and 3) cannot be evaluated as strings.
"if (val == '1') {" becomes "if (val == 1) {" .

Warning : We could also leave this file as it is, and make sure the
value returned in AJAX is a String.

issue #170

- The "New data added to this project will be kept [...]" label has been
removed.
- The label indicating a space's retention limit and purge policy will
now be set in application.properties, as 'purge_msg' in the project
variables.
- Every project's purge message will be displayed in its individual view
(Under the "Current space: xxx" label).

The get_purge_mail has been reworked to avoid redundancy.

issue #161

New "Send mail without extension" button, that sends the purge demand
mail without the content related to retention extension.

The log instruction might only work in the test environment.
I forgot to remove this line in the last commit, my bad.

2 search criterias have been added, filter on space (project space_id)
and delay exceeded (yes or no).

And there is a new "Refresh list" button to handle the new filters.

Merge branch issue#154 with dev

See merge request !90

The projects count has been updated to ignore the hidden projects if
they do not appear in the list.

issue #154

1 import was missing to use the new data type "ng6space".
(So the space selection is a nice dropdown menu, instead of a simple
textfield.)

# Conflicts:

Same as last commit.

issue #151

There was a if( xxx = yyy) instead of a if( xxx == yyy) in
class.tx_nG6_eid.php .

PS: If asked, I will deny everything.

issue #151

I don't see any difference yet, but the master version of this file
return no result table, and this version does.

I might revert this commit if it is useless.
