C++ API

• Database::get_average_length(): Add this as an alias for Database::get_avlen(). In git master we've added this as a preferred new name - adding it to 1.4.x too will make it easier for users to update to using this.

• Database::get_spelling_suggestion(): Optimise edit distance initialisation loop to significantly reduce the cost of a typical edit distance calculation.

• Fix query expansion on sharded databases. The mechanism for passing in which shard a TermList is from wasn't hooked up and as a result we'd always think it's from the first shard, meaning the statistics would be wrong and that our suggested terms may not have been as good as they should be in this situation.

documentation

• Update doxygen HTML headers and footers to resolve issues with some interactive features of the API docs not working. Reported by Enrico Zini.
