Home Location page

[AntonKhorev]

This adds a home location page with its own URL similar to what's suggested in #670 (comment), without sidebar and extra controls. Instead of /:username/home I use the path /account/home because it's easier to implement, no need to check :username.

A link to this page is available on every other page with the user dropdown menu. This fixes #1810.

It's possible to leave this page for another map page. In this case the javascript controller removes the home location marker. This fixes #669 and #670.

Described functionality works perfectly. Redirection is flawless in all situations (browser back/forward button navigation, page refresh, browser link navigation, app menu navigation). Home icon appears in /account/home and disappears as soon as a user is redirected to another page. The only question I have, wouldn't it be better if we used I18n translate function I18n.t instead of hard coded text while using click_on and assert_text in tests. In that case, even if, in the future, we decide to change texts, it won't break tests.

Changing names of i18n strings will break tests then.
