Using discovered jackson2 modules

[vojtechhabarta]

EDIT: Configuration of this functionality was changed in v1.29.355. See #183 - section "Jackson2 modules".

This PR fixes #110.

When Jackson2 library is used with some Jackson modules typescript-generator reflects automatically these modules. For example project can have this dependency:

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-hibernate5</artifactId>
    <version>2.8.6</version>
</dependency>

and in this case bean properties marked with @javax.persistence.Transient annotation are ignored by Jackson in runtime and also by typescript-generator when generating declarations.

This functionality can be disabled in configuration:

<configuration>
    <jsonLibrary>jackson2</jsonLibrary>
    <disableJackson2ModuleDiscovery>true</disableJackson2ModuleDiscovery>
</configuration>

Complete example is in sample-maven.
