Start to fill gaps as defined in the backlog

[egamma]

Progress on this backlog described in #32. The PR got larger than I wanted, sorry.

• added a folder with manual tests
• added several settings, support to disable work around to disable the NoUnusedVariableRule

                "alwaysShowRuleFailuresAsWarnings": false,
                "ignoreDefinitionFiles": true
                "configFile": "../tslint.json",
                "disableNoUnusedVariableRule": false

• enabled tslint
• add some stricter TS settings like noImplicit any
• clean-up code to remove the left over tslint 3 support
• documented dev setup
