Migrate {{#isInteger}}, {{#isLong}}, {{#isDouble}}, {{#isFloat}}

[jmini]

Fix generated code: example EnumTest.java Line 59 on master branch

IS:

@XmlEnumValue(1) NUMBER_1(Integer.valueOf(1))

SHOULD BE:

@XmlEnumValue("1") NUMBER_1(Integer.valueOf(1))

This pull request migrates following:

• {{#isInteger}} ... {{/isInteger}}
• {{#isLong}} ... {{/isLong}}
• {{#isDouble}} ... {{/isDouble}}
• {{#isFloat}} ... {{/isFloat}}

Inside {{#enumVars}}..{{/enumVars}}

[jmini]

The explanation why {{#isInteger}} ... {{/isInteger}} is migrated to {{#is ../../this 'integer'}}..{{/is}} inside {{#enumVars}}..{{/enumVars}} can be usefull for other migration cases.

I have documented it in the wiki, in this new section: Evaluate a path against its parent context

After #38 and #36 this is the the last change in order to be able to generate the JaxRS sample of the swagger-codegen repository. (JaxRS generators were introduced with #29).

When this pull request is merged, I will update the scripts for the continous integration and thesample folder. Everything is prepared on patch-9 branch.
