HTML rendering: fix space between lines that contain small printed letters.
space was too much. now it acknowledges the size of the fonts used in the current line.
winforms generator: if there is no label for a column in the grid, use the name of the column instead
fix database structure: add a_ledger_number_i to unique key of table a_ep_match.
this allows donors to donate to two charities. otherwise you get a constraint error.
the previous commit should have had the bug number assigned, for the fix to petra.xml
