New feature: ADMINISTRATION panel

[deloittem]

New feature to add: ADMINISTRATION panel

The administration panel should be useful to customize IRMA directly from the WEB frontend. The first example is for the TAGGING feature: having a tab to manage the tag(s):

• Listing all available tag(s)
• Add new tag(s) directly from the administration panel
• Same with removing

Later, more feature could be added in the administration (e.g. managing YARA rules etc)
