Ability to turn off or manually restrict 'include auto completion' feature

System info:

• Sublime Text version: 3210
• Which system are you on: Ubuntu 16.04
• Clang version: 7

What happens:

Keeping admiring the plugin, I have a few perf issues. One of them is related to includes.

I'm working on a project inside a large repo and my files can #includes files from other projects. Specifically, there almost always are -I flag with root repo path in compiler flags. I had to write my own plugin to collect only required folders for header lookup (just listing them in the project config).

Now I've noticed that ECC tries to search headers on its own and 'goes through' that root folder. While this, 'plugin_host' gains lot of processor time. I am looking forward to ability

• either to turn off the include autocomlete function at all
• or to restrict the folders/subfolders that should (shouldn't) be searched in for headers.

Log that illustrates the issue:

Yes, this feature is a bit half-baked and you raise a valid point. I was sure that I allow turning this off, but apparently not. Will add a switch. If you have ideas on how to implement this better feel free to contribute or just start a discussion in a new issue.

Thanks!

By the way, does this feature reads all the compile_commands.json to fill the folder list? Is it on plugin startup or at the moment autocompletion starts?

I will close this issue to continue talking about it in #706 if you don't mind. Hopefully I will get to actually implement this in a proper way some time soon.
