It's used there, so we got weird build errors if krita wasn't
built for some reason (mostly because of a missing libgsl). Add
our own tried, tested and true shared pointers to libglobal so
I can start using them in a new import/export plugin registry.
And finally, enable exceptions globally, since libglobal now
also needs them.

Summary:
This allows the guides tool (for example) to allow click and drag with touch
through the synthetic mouse events, while the same mouse events can be
rejected by the freehand tool.

The only occurrence of synthetic mouse events I've found is in Surface Pro 3
touch events.

This should allow smudging that creates semi-smooth gradients.

Added on request from new users for whom this preset is not self-evident.

Qt has a bug: when we Ctrl+click on an item, the item's selections gets
toggled on mouse *press*, whereas usually it is done on mouse release.
Therefore the user cannot do a Ctrl+D&D with the default configuration.
This patch fixes the value returned by selectionCommand() callback to
fix this issue.

Summary:
Only able to move selection one pixel at a time, for now.

Integrates with current stroke framework, so if a move is currently in progress, will move a selection or group. Otherwise it defaults to moving current layer or selection.

Hide occasional blots from tapping the pen and short touch events.

And extensive extra notes in the readme for cross-platform builds

The Layer commands provided by the main menu will be grouped into the
commands provided by the layers box.
