Add mybatis-typehandlers-jsr310

[making]

It would be nice for spring-boot-starter to manage mybatis-typehandlers-jsr310.

I'd like to use managed versions like following:

    <dependencies>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-typehandlers-jsr310</artifactId>
        </dependency>
        <!-- ... -->
    </dependencies>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>1.5.2.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>org.mybatis.spring.boot</groupId>
                <artifactId>mybatis-spring-boot</artifactId>
                <version>1.3.x</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

@making Thanks for your contributing !!
We have a plan for merging jsr-310 typehandlers into the mybatis core module at next release.
For details see mybatis/mybatis-3#974.

@making We merged jsr-310 typehandlers classes into the mybatis core via mybatis/mybatis-3#974.

Thanks.
