Emergency sell all feature

[sjanel]

Could be a good idea to implement a general sell-all (all coins) with only optional list of exchanges as argument. Based on list of preferred payment currencies, coincenter is able to sell all non-payment currencies into them in a fast way (probably with taker / nibble strategy, configurable or not).

Hello @andrewcz

If you would like to start working on it, to have an example of which files to modify in order to add a new command line option, you can see this recent commit, especially the files located in engine sub directory.
