Added the following blocks

[emil01]

INPUT_PULLUP:
A standard block that can be used to configure any pin as either INPUT,
OUTPUT or INPUT_PULLUP

Useful for interfacing switches and other devices that require a pullup
resistor

Liquid Crystal library:
Added blocks for:

1. Begin()
2. print()/println()
3. clear()
4. setCursor()

Thereby allowing basic LCD functionalities.

Thanks a lot for the contribution. I will be travelling until more or less the end of the month, so I am afraid I might not be able to review the PR until I'm back. Sorry for the delay, but I do look forward to try this out!

No worries. Have a safe trip

I'm really looking forward to this pull, since we're planning on using it with our arduino's at school. Any chance this will be added in the next few weeks? No pressure, just asking =)

@JorenVandenBergh You can download the my compiled version for windows from https://www.dropbox.com/s/2yto6zwbq1tb2qo/liquidCrystalAndInputPullup.zip?dl=1

Note: once you run the program, open preferences ( ctrl+comma). If you get a notification which says app not running, you will need to manually run the start.py file from command prompt.

1. Open command prompt using ctrl+r
2. Type cmd and press enter
3. Type python /start.py
   If started successfully it should open a browser with the app you can close it and run the ardublockly_run.bat to start the program.

Do let me know if you are facing any issues
