[fix] issue with applying new MT4 settings after update.

v1.1.0.4

starting from now TickInfoLast will not make any calls to MT4, it will return internal buffer instead. But, if you want to collect prices you should add symbol to watch list by making a very single call to SymbolAdd. Then during whole WebAPI runtime it will collect prices for you into internal buffer. Keep in mind, this is not a history, only most recent prices for each explicitely monitored symbol. By default, symbol will be in market watch when there are open trades on it. Otherwise, you will not see prices until add symbol to watch list.
now there are two methods :
- TickInfoLast/{symbol} - request prices for specified symbol only
- TickInfoLast - request prices for all monitored symbols
