Patched a bug with WrittenContent popovers and added popovers to Art Forms

[uptudev]

Noticed a bug with the popovers on Written Content, and went ahead and implemented popovers on Dance, Musical, and Poetic Forms while I was at it. Currently the Art Form popovers do not highlight the author civilization or historical figure, as I would likely need to do something way more intensive to retain that information; it isn't kept in the XML files, sadly. Currently it trims some words from the first sentence of the Art Form's description.

Bug Details (Fixed in PR)

When hovering over an object of the type WrittenContent, instead of the intended popover displaying, the server panics and logs a message to the console about popoverWrittencontent.html being missing; the correct file is popoverWrittenContent.html (with a capital 'C').

Changelog

Fixed WrittenContent popover bug

• Modified: server/server.go - Fixed the typo which caused the above webserver panic.

Implemented popovers for Art Forms

• Modified: server/server.go - Added routing for new popover HTML.
• Modified: templates/layout.html - Added popover script to objects of art form type.

• Created: templates/popoverDanceForm.html - Added popover HTML for Dance Forms
• Created: templates/popoverMusicalForm.html - Added popover HTML for Musical Forms
• Created: templates/popoverPoeticForm.html - Added popover HTML for Poetic Forms
