- Removed some redundancy in the help texts.

- Added expression parsing to the offsets. You can now use expressions like w/2 or h-3. Supports up to two operands. Supported operators are +, -, /, and *.

- Removed anchors. Being able to set the base offsets renders anchors redundant, plus they only interfere and make things unnecessarily complicated and/or confusing. May reimplement if deemed necessary.
- Base offsets are now required.
- Moved destination to the end of the argument list because it is still optional.
- Set UseShellExecute to "true". There's no reason to use "false" in this scenario.

- Fixed drag-and-dropping making the program confused about the search location of offset setting tools.

- Decoupled tool from SetPNG. Can now supply either GrabPNG or SetPNG. Program will prioritize the former since it's newer.
- Added proper description in the CLI.
- Improve feedback when processing images by printing that in the console for each image along with its name instead of a generic "Processing..."

- Bumped version to 2.0.2.

- Removed unused code.
