Code Cleanup

[fuzzard]

Just sets all files to use spaces instead of tab. The majority already uses this, so figure it all might as well match. I guess im a bit ocd, so feel free to reject. There is absolutelly NO functional changes in the whitespace fixup.

The execution change in Update() is to create the lock earlier, and exit if tuner discovery failure earlier. should have very little affect, but figure it might be a little nicer.

decided to push some more changes to this PR. Based around modernising existing code.
Changes for loops to auto ranging, which reduces the temp variable usage. Cleanup some unused variables. Changed memset for 0 initialization to aggregate initialization (http://en.cppreference.com/w/cpp/language/aggregate_initialization)

I know your a busy man, but mind having a look when you have a spare moment.

Just had a quick look, lots of stuff changed, not enough time to do a real review.

Please update the changelog and do an addon version bump. Then we can merge stuff (and will see what happens).

[ksooo]

Could you please remove the merge commit and do a rebase instead?

[fuzzard]

version bump and changelog added.

There is a lot of churn, mostly to do with the whitespaces commit. If its preferred i can just drop that. It was just to make all files uniform, and really isnt that important.

[ksooo]

For the changelog, not every single code cleanup change needs to be documented in detail. A one liner "Code cleanup (no functional changes)" would imo be enough.

Leave the whitespace changes in, makes sense. Just remove the merge commit...

[fuzzard]

Think thats all better.

I do appreciated the help, thanks.
