Build script (on macOS) folder and fontname issues

[luistoledo]

On macOS, executing the build.sh script fails in three ways:

1. temp directory

   build.sh: line 48: ../temp/newfile.txt: No such file or directory
   pandoc: ../temp/newfile.txt: openFile: does not exist (No such file or directory)

   Fixed by creating an empty temp directory

2. output directory

   pandoc: ../output/Manifestos_for_the_Internet_Age-20170607_111323Z.pdf: openBinaryFile: does not exist (No such file or directory)

   Fixed by creating an empty output directory

3. font name

l.76 ]{HK Grotesk Pro}

pandoc: Error producing PDF

Fixed by changing the font name at line 67, from "HK Grotesk Pro" to "HK Grotesk"

--variable mainfont="HK Grotesk" \

Solution:

- The first and second issue can be avoided by the same script, checking and creating the folder before the execution.
- For the third one, either change the script file or upload the exact font file
- Also the font installation can be automatized by copy the font files into the /Library/Fonts folder
