- Integrated ViewTask and ViewText completely.
- Obsoleted Table.{h,cpp}, Grid.{h,cpp}, grid.t.cpp
- Fixed ViewTask rendering bug that caused the full width to be used every time.
- Broke out View into ViewTask and ViewText, where the former uses an
external std::vector <Task> as storage, thus eliminating the additional
copy, and the latter that duplicates data and color into 2D vectors
for rendering non-task data.
