#1801 Fix a lot of typos

[Bewied]

I did https://sourceforge.net/p/scintilla/code/merge-requests/15/ before I saw somewhere else that you don't receive Pull requests (why?)

Please find attached a patch that should be appliccable to the current tip(?) of the repository, made via hg export.

This fixes a lot of typos. Credits go to the authors of codespell.

I have limited time so only monitor a particular set of data feeds. Pull requests were forced on projects by SourceForge with no customisability and poor usability. If someone wants to volunteer to check for pull requests and turn them into tracker issues then that could be investigated.

Lexers (all files in the lexers directory) should only be modified by people directly concerned with those languages. There is too much scope for regressions and merge problems which should be balanced against the small benefit of fixing spelling. Modifying these files gives a false impression of maintenance activity. Likewise the lua directory for SciTE should not be changed.

"wanna" is common English.

The two occurrences of "won't" in ScintillaBase.cxx are fixed by [35a130].
