When an explicit parsing error is encountered and a CompileError raised,
apply the changes to the context state. This way, the rule that catches
the exception (e.g. Statement or Until) knows where the error occurred.
Also, changed "Expected" errors to be reported at the end of the
previous non-whitespace token.
Many completion snippets insert more than just the name. For example,
the object completer inserts the braces and places your cursor inside
them automatically, to save some typing. However, if you're changing the
class of an existing object, this isn't what you want. Changed so that
if the next token is '{', only the name is inserted.
Made similar changes to the property and signal completers.
Don't invalidate everything every time, otherwise we rebuild everything
even when no file has changed at all. With e.g. Vala this means more or
less rebuilding the entire project with no incremental builds.
A lookup tag with no type attribute would crash the decompiler, even if
that was valid. This wasn't caught by the tests since blueprint never
generates such XML.
Also fixed a bug in the tests that caused decompiler-only tests not to
run.
When putting CDATA into the output, any instances of ']]>' in the text
are replaced with ']]]]><
