fix typo in message
pdb: use if defined $proc->{outargs} not if exists $proc->{outargs}

in app.pl and lib.pl because pdbgen copies this stuff round so
generically that it always exists. Fixes a ton of perl warnings.

Added internationalization macros to selection-to-path-dialog hidden parameters.

Bug 708033 - Add paragraph support for the long description in pdbgen

Single newlines in procedure descriptions are still considered normal
spaces. But 2 newlines are transformed into 1 newline. 3 newlines into
2 newlines. And so on.
This allows for a start of nicer output in the procedure browser or C
file comments (and consequently in generated html doc).
tools: remove some doc newlines in context.pdb

Add whiteish borders around the align icon arrows.

Bug 709048 - improvement of gimp-layer-add-mask procedure's doc.

Also make nicer output and list formatting with the new pdb paragraph
feature.
