Merge pull request #14 from khaledhosny/master

Update documentation
tx-related tools. Fix bug in uforead.c. Logic set a pointer to the first opList in a contour. When the opList was resized, the pointer was not reset, leading to some very strange outlines in the output.
Add CheckOutlinesDialog.py back to the FontLab Macros. This now works with the latest version of the FDK
added new tool to do overlap removal. Works only on UFO fonts. This uses Frederick Berlaen's booleanOperations github library. This is still work in progress. The behavior is not the same as the FDK checkOutlines tool. One difference is that in checkOutlinesUFO, contours are merged if a corner point on one outline lies on the path of the other outline; this does not happen in checkOutlines. There are also some bugs to resolve. When two curves intersect, if they are long and nearly flat at the intersection point, checkOutlinesUFO will insert a short straight line at the end of the incoming curve. Another is that if there is a small jog in a path ( two consecutive near right angles, with a short path between), it will get sanded off in checkOutlinesUFO.  The output is written to an alternate layer in the UFO font: to see the output, you need to use 'tx' to copy it to a new font, ufo or Type1.
Bug fix: dictionary keys need to be integers so that the items can be properly be sorted later
Fixed problem in name.c with missing end bracket
Update .gitignore files to omit temporary build directories
Restore output directive for the built programs. This location is required for the script BuildAll.sh, which copies them to the final location needed for the FDK to work when installed.
Removes duplicate FontLab scripts. These scripts are available at https://github.com/adobe-type-tools/fontlab-scripts
Add support in makeotfexe for kern pair value format A, as documented in the feature file syntax specification.

  Removes duplicate FontLab scripts. These scripts are available at https://github.com/adobe-type-tools/fontlab-scripts
Address issue #4, "Licensing clarifications in headers". Replace old Adobe license and MIT license references with Open Source Apache 2,0 license references.
Rename DONT_USE_WIN_LINE_METRICS to match the spec

The spec[1] uses the name USE_TYPO_METRICS, so using the same name here
is less confusing.
