#1556 Misc spelling errors
Debian's QA tool Lintian has flagged a few spelling errors in Rosegarden. Lintian isn't a spell checker but contains a blacklist of common misspellings. The attached patches fix both the source code in the .cpp file and also the English text in each of the .ts files so that translations aren't flagged as fuzzy (which I think is the best thing to do in this case).
assigments → assignments
ammended → amended (comments only)
cancelation → cancellation (This one can be debated: en_US, like en_GB, prefers cancellation although cancelation is sometimes found and those who advocate spelling reform (Websters dictionary) will even claim that cancelation is preferred, contrary to standard usage. When it comes to matters of style, I've grown to trust lintian!)
Inglish are hard too spel.
I applied all three patches, verified that everything still builds (of course it does), and verified that this tweak went unnoticed by the translation tools. Looks like a win to me, so I committed the whole shooting match as 15149.
Thanks!
