Add nls support in config files, add pt-pt translation

[iled]

These commits add a complete Portuguese (pt-pt) translation to CMV, including:

• all core widgets
• viewer main menu
• other config files
• page titles

viewer.js and the other config files didn't have support for nls, so it was also added. All input text included in each config file is stored in nls/main.js. E.g.,

// http://dojotoolkit.org/reference-guide/1.10/dojo/i18n.html
define({
    root: {
        basemaps: {
            ...
        },
        bookmarks: {
            ...
        },
        otherWidget: {
            ...
        },
        viewer: {
            operationalLayers: {
                damageAssessment: 'Damage Assessment',
            },
            titles: {
                header: 'Configurable Map Viewer',
                pageTitle: 'Configurable Map Viewer',
                subHeader: 'make it your own'
            },
            widgets: {
                bookmarks: 'Bookmarks',
                directions: 'Directions',
                draw: 'Draw',
                ...
            }
        }
    },
    'pt-pt': true
});

Other changes included:

• dropped a deprecated layer reference in config/identify.js
• normalized keys to camelCase format, in cases where they were PascalCase or kebab-case
• add Null Island bookmark, as suggested by @tmcgee

I started this translation by forking a repo by @carrbrpoa.

@iled travis found some eslint errors. indentation in some of pt-pt resource files and a 3 missing semicolons 😉 in config files. the errors are spelled out in the log here. If you run the grunt lint command on your local copy, you can see the errors there too.

@DavidSpriggs thoughts?

[iled]

Fixed eslint errors.

Reverted renaming Esri basemaps.

@iled all looks good to me.

Let's see if @DavidSpriggs has any comments about the approach I recommended for i18n in the config files.

[DavidSpriggs]

Looks good. Pulling in the i18n works for now. If we ever want pure Json config files we will have to rethink this approach. This occurs in other places too.

Thanks @iled !
