Add support for USD price lookup of any altcoin

Browse Source 
-Market sync now sets the last USD price based on the default market pair even if it is not BTC
-Removed the coindesk api which was only really useful for getting the USD price of BTC
-Added a couple coingecko apis which are used to get the current USD value of the default market pair
-Updated the readme, settings file comments and info/api page with better verbiage regarding the market price which was previously only measured in BTC
