MATH should add escape symbols

[1470429149]

Confirmation

• I checked the Issues and Pull request tab for any existing issues or PRs.
• My Feature Request is for PlaceholderAPI and not any expansion or other plugin.

Type

Minor Code improvement (Won't affect Servers)

Description

Sorry, I can't find the MATH extended formula submission question window

Because some variables will contain {}
For example:
%objective_score_{apa}%
So use %math_{objective_score_{apa}}/100%
will return an error because MATH treats {apa} as a variable rather than a parameter in the variable.

Also, {} inside bracket placeholders won't work either way, as it breaks placeholder parsing in general.
