7c0ef111ea 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.

364bd25fa8 #48 add handling of inline image data to pdf content parsing 
an inline image in a pdf content stream starts with the bi tag, then id declares the start of image data and ei the end. attempting to parse the bytes after the id tag as usual resulted in errors. this change adds special case handling for inline images.

Merge pull request #3 from GowenGit/master 
letter boundaries - todo: review changes for non latin characters, it seems like we need both the bounding box and the origin to be stored for each letter since the origin is on the baseline while the bounding box can extend below.
