Execute method:should be ability to copy output data (at least addresses), needs add copy icons

FireFox : screen Execute Method isn't scrollable if multiply outputs present

@vbaranov
NW isn't usable in popup mode if user want to call method with two and more input parameters. User needs fill out two fields but can't copy/paste two parameters because the input field's value is lost after each closing NW

Execute method returns incorrect value for uint32 and more. Value 'cutted' to uint16
Contract 0x8ba3f8618a33cd3f155477e889295a4c5ab52ae4, Sokol
Method returnUint which simple returns input, input data 11223344556677889911223344 , output 11223344556677888000000000
