Add option to disable Apple-converted-space
font collection class missing from Mac framework
Added unit test for #377
Changed _loadAvailableFontsIntoOverrideTable

instead of just having fonts overrule a previous override the strategy is now:

- add overrides with font descriptors sorted alphabetically first by family then by name
- if no override for combination of family, bold, italic traits exist, add it
- if one exists, replace it if the font name is shorter.

This prefers e.g. Helvetica-Oblique over Helvetica-LightOblique even though the -Light comes alphabetically before the font.

fixes #377
fixed Mac framework

- needed the -ObjC linker flag to include category methods from DTFoundation in itself
- removed superfluous static lib linking in MacUnitTest, since these methods are all bundled in the Mac Framework
Adds a variable "shouldAddFirstLineLeading" to DTAttributedTextContentView (and so to
DTAttributedTextView). I found that DTCoreTextLayoutFrame's _noLeadingOnFirstLine was
always no because layout frame was always being created anew and _buildLinesWithTypesetter
was always executed before it was set. This change causes _noLeadingOnFirstLine to take
the intended value immediately on layoutFrame's creation and so leading is applied or
not according to preference.
Added paragraph finding unit test
simplified NSString+Paragraphs a little
