QRegExp matching is quite expensive, and has to be done for every file
in the project directory tree against all possible suffixes. Optimize
for the common case that the pattern is "*.suffix" by doing a
fileName.endsWidth(suffix) in this case.

This speeds up loading of examples/declarative/declarative.qmlproject by
about 30%.

TextEditor will now recognize an UTF-8 BOM.

A setting to determine what to do on saving has been added as well - the
options are "Always Add", "Keep Already Present" and (mostly for
completeness) "Always Delete".
Note: if encoding is "System", "Always Add" doesn't work, because there
is no API to know what the System encoding is.
