DeltaQt 0.4.0 pre1 发布，改进记录：
1. The addition of the VIDE dataset to packaged DELTA datasets.
2. A minor bugfix reading character notes. Minor optimizations (parsing is ~12% faster than 0.3.0).
3. An updated example application. Note: this was originally going to be version 0.3.1, but the addition of VIDE to the package warrants a minor version increase rather than a revision increase.
4. VIDE is a complex dataset that stresses' the parser (it takes considerably longer to parse than the other included datasets)
