-												move classes to new projects

to make the project more useful and expose more usable classes we're rearchitecting in the following way. code used to read fonts from external file formats like truetype, adobe font metrics (afm) and adobe type 1 fonts are moving to a new project which doesn't reference most of the pdf logic. the shared logic is moving to a new flat-structured project called core. this is a sort-of onion type architecture, with core being the... core, fonts being the next layer of the onion, pdfpig itself the next. this will then support additional libraries/projects as outer layers of the onion as well as releasing standalone version of the font library as pdfbox does with fontbox.

-												add writing methods to truetype tables #98

since we have verified the problem with the characters not appearing in acrobat reader isn't the checksum (other files also have invalid checksums but work) it seems likely the issue is with the os/2 table.

this change moves the logic for writing out the cmap table, the format 6 cmap sub-table, truetype table headers and the os/2 table into the classes themselves. now we can write an os/2 table and we've tested that the output matches the input, we can overwrite the os/2 table in order to work out which of the os/2 errors is causing our font to be invalid.

the writeable interface should be added to more and more parts of the codebase so that writing, editing and document creation become first class citizens rather than hardcoded additions.

this change also adds the macroman (1,0) cmap subtable to edited fonts so that it is present for consumers which expect it.
