Made possible many examples to run in 512 bytes ram chips, fixed few …

…typos, missing F() macro calls and other minor improvements
(Redid the changes from latest clone branch to ease merging).

@TMRh20 What should be done with this?

[TMRh20]

Well, I should probably thank @fab672000 for making these changes, but I try to test everything mysef, at least minimally before pushing to the master branch.

The only question I have after visual review is regarding the need for the jamfile but was going to leave that for after.

Unfortunately, I haven't been able to do the testing, so the changes have just been sitting here waiting. As soon as I, you (or anybody) can do an 'official' run-through of the modified examples, and post confirmation that everything still compiles and works properly, they can be merged immediately. The new example looks good to me also.

[fab672000]

Just to confirm I checked before submitting that all the changes do compile fine as far as I can remember.
Then, I also did test most of them if not all to be confident about all of these.
Please note that many changes repeat from one example to the other, changing only the title of the example being most of the difference. Also, in the worst case scenario of a regression, should a carriage return be missing or the like, it's quite easy to identify as opposed to the knowledge of the ram saving macro use or similar techniques imho.

Also I kept the existing Jamfile in examples because I was not sure if they are still used by some, but personally don't use them so feel free to trash them.

The most important changes are the one in the source code, not the makefiles use for which you would probably know better than i currently do.

These changes affecting directly the RAM utilization are the significant improvement to capture here.
I also fixed some missing macros that were forgotten last time you or someone else in that branch started to do similar changes, hope it helps having a 100% clean status on ram use in the examples now.

Finally please note that code can be much more improved for one example there where i decided to not optimize it because of lack of time for testing.

The change is trivial though and I'll come back to it in my leisure time as soon as i can test it.

[Avamander]

I tested the changed files, all compiled fine. (I did not test the Jamfile file)

@fab672000 Thanks!

NP, I'm glad I could humbly help ; thanks to both of you for doing such a great job on that fork !
