Alternative speed limits changes
WebUI: Use correct max ratio value

Closes #183.
WebUI: Never show scrollbars in rate limits dialogue

A different DPI setting might make the elements in the dialogue big
enough to make the scrollbars appear, but not big enough to make them
useful. So, never show them.
WebUI: Make transfer info look like in the regular UI

The string for the transfer info was not translated as it should have.
Drop it completely.
WebUI: Define some functions on load

These function shouldn't be called when the page is not loaded yet,
so it makes sense to define them later.
WebUI: Use relative sizes when saving panel height

This should prevent situations in which the properties panel completely
covers the transferlist on page load.

Save also the height whenever the window is resized since that changes
the height of the panels without saving the height.
Follow project coding style. Issue #2192.
WebUI: Don't cache transfer info values

In this way speed limits are instantly updated.
