WIP: Autocomplete suggestions in Editor

[preetham]

These series of commits implement autocomplete suggestions while typing in the editor.

• Library provided by ace "ext-language_tools.js" is used to implement autocomplete suggestions.
• "syntax_gen.js" is added to generate snippets from nodetypes which act as suggestions.
• checkSnippets() in "syntax_gen.js" checks for new additions in nodetypes and generates accordingly.
• generateNodetypes() is run at the startup of server to generate/add autocomplete suggestions.

The overall of the patch is totally good! It works as it should be.

As we have talked over IRC it would be perfect if we have some changes in our code.

1- Changing the shortcut names to be easier to be understood

Example: We could replace these: gpioread and gpiowrit to GPIO Reader and GPIO Writer

Something more readable for human eyes.

Also, we could change the color of the font to be white or something clearer.

2- Also, we could put the descriptions of the nodetypes in the white box in the right. This would teach the programmer what the nodetypes do.
