New feature: TAG(S) SETTING

[deloittem]

New feature to add: a TAG SETTING at SELECTION view

For example, sometimes we have a collection of file(s) linked to a specific case and we would like to directly submit them all and tag them with a tag related to this case.

In case no TAG is specified: add a feature "DEFAULT TAG" which automatically use the default tag for each file (e.g. tag UNKNOWN by default if no tag(s) have been specified)
