Vue Front End updates (minor)

[jnharton]

Updates to global CSS. Added new page/component and made relevant changes elsewhere.

• Add: Military/War page (vue component)
• Add: table style css for the military page to global.css
• Resolve: Issue with the nav bar being mangled due to an element change from div to nav by simply selecting the nav element
• Resolve: commented out embedded app styling in App.vue to keep it from messing up the text layout or overriding stuff from global.css
• Resolve: necessary and relevant changes made to routes.js and the SidebarNav Vue component
