Remove TextGrid functionality

[DennisFriedl]

For example loginToTextGrid.xql and checkTextGridLogin.xql

[peterstadler]

there are also references to textgrid here

Edirom-Online/add/data/xqm/util.xqm

Lines 138 to 149 in 52a8c2f

	declare function eutil:getDoc($uri) {
	if(starts-with($uri, 'textgrid:')) then(
	let $session := request:get-cookie-value('edirom_online_textgrid_sessionId')
	return
	doc('http://textgridlab.org/1.0/tgcrud/rest/' || $uri || '/data?sessionId=' || $session)
	) else (
	doc($uri)
	)
	};

and here

Edirom-Online/app/controller/LinkController.js

Lines 119 to 120 in 52a8c2f

	if(config['sort'] == 'sortGrid')
	positions = this.application.getController('desktop.Desktop').getGridPositioning(uriWindows.getCount() + i);

I think this should also be removed?

although d44dfd0 removed the xql files the code references above probably should be revisited
