Show small hints and description on mouse hover

For example hovering "Premium" gives you a small explanation of what it means. Useful for all the items in the form of the MakerPage.
In addition, there could be a on-by-default hint box over the Token TextField that reminds users to back it up.

Mostly implemented in the latest PRs. Some more tips could still be added in the Order and Contract boxes.

Most critical ToolTips are already in place. As of now it is a matter of double checking all over the whole app and see where some tooltips could still be useful if added. One could think of adding ToolTips in:

1 - Rows of the OrderPage (Order box). (E.g, tapping on Premium explains what premium is)
2 - Different steps of the TradeBox (Contract box). (E.g, tapping on copy to clipboard says 'copied!')
