ystarnaud 3ae5f97b94 Algorithm Switcher Update 
Updated Algorithm switcher to change on pool rather than on algorithm.
This way if, for example, 2 pools use the same algorithm but different
GPU settings, the settings will be applied when changing pool.

Additionally:
* Included a "common" algorithm type in API pool/profile listing. For
example using "marucoin-mod" will return "X13", "darkcoin-mod" will
return "X11", scrypt + nfactor != 10 will return "NScrypt", etc...

* Added "kernel" config option to be backwards compatible with other
miners' configs.

* Added a few algorithm aliases: x11mod -> darkcoin-mod, x13mod ->
marucoin-mod...

* New config keyword: "includes", which holds an array of include files.
This is to counter the JSON limitation not allowing multiple values with
the same name, thus preventing inclusion of multiple files.
