Slows typing rendering

[kmisiunas]

Problem: when typing or deleting fast ST3 stops rendering text. This happens on slightly weaker machines. When I switch off the plugin the lag is gone.

Possible reason: SublimeWritingStyle checks document after every character change. A costly operation.

Proposed solution: adding a delay between checks. Linter package allows to add 500ms delay that seems to fix this problem with linter.
