misc: set `algorithm` for pool in example.conf.

Also finish up what was started in f2934d8afd4f0fdce7597e2b1f38a7a29337e5d3
Update sgminer.c

Minor changes to variable declaration.
Should reduce the number of warnings by about 5.
Update sgminer.c

One small change to work well with previous ones.
Number of warnings now is 151, down from 157.

Still a long way to go. Most of the serious warnings are related to variables in miner.h, which is so intertwined with everything else that I fear of breaking something or making performance worse if I touch miner.h too much.
Merge pull request #187 from Bllacky/patch-5

Reduce the number of warnings by about 5 (Update sgminer.c)
core: revert two of the changes in Bllacky's pull request #187.

`ndigits` is actually an int, used as a field width specifier in
snprintf().

s is an extensively-used pointer.
Update miner.h

Variable declaration. VS seems to like size_t instead of int for certain variables.
Merge pull request #189 from Bllacky/patch-7

Update sgminer.c
config: write pool name and description to config.
Fixed (pool) algo selection.
Added algorithm name to 'pools' API command.
Merge pull request #193 from troky/master

Small fix and upgrade
ui+api: ask for pool name/description/algorithm when adding pool from NCurses/API.

Closes #116.

This is trivial and shouldn't be so hard: it required modifying
functions in both sgminer.c (for NCurses stuff) and api.c. There is
much code repetition, since the NCurses interface is hard-coded in.
Removing it would simplify things greatly.
api: bump version, but allow name/desc/algo to be missing when adding pool details.

This will have unintended consequences, since API clients are sure to
send pool details without name/desc/algo. pooldetails() will allow them
to do that, and add_pool_details() will fill the pool structure with
NULLs.
api: check if name/desc/algo are NULL and fill with defaults if so.

Defaults should probably be specified elsewhere.
There should be a constructor for stuff like this.
This shit is really bringing me down.
api: set algorithm properly on addpool.
misc: Bump version to 4.1.270.
api: Bugfix, bump version to 4.1.271, initialise name/desc/algo in addpool() so checks for NULL work.

Otherwise API "addpool|a,b,c" command segfaults (access uninitialised
memory address).
misc: Add Michael Fiano <mfiano> to AUTHORS.md.

Tested tecent name/desc/algo additions to API, helped find a segfault
condition.
misc: FAQ cleanup.
misc: moved from veox/sgminer to sgminer-dev/sgminer
