Market works

Some charts removed while others added to work it.
Fixed the USD and BTC problems in issue #6
BTC is displayed in satoshi as netdata doesn't allow more then 4 decimal places for numbers 1.0 and under. 4 decimal places is currently the limit.
Seperated Market cap and Liquidity for now as the values were so far apart it didn't really perform like a chart.
Service added and made much like getinfo (thanks to @fooforever for his service setup)
USD is displayed with 4 decimal places as thats the limit in netdata. Better then listing in microcents.
Made a few copy boos boos but fixed them up (multi commit updates)
Market Changes are one decimal place do to the reason of netdata decimal limits. In order to prevent netdata from rounding the decimals you have to multiply the number before hand and then divide it in the deviser of DIMENSION. Without this we'd have numbers rounded up to the decimal place.
Other fixes may be present.

Changes are welcome
