[Bug/Feature] Handle Curly Brackets Properly

[ColaIan]

Description: As title

How to reproduce: Use PlaceholderAPI placeholder in Math expansion

Example: Use ${viewer math_{mmoitems_stat_movement_speed}*1000}

[18:39:55 WARN]: [PlaceholderAPI] [Math] Invalid Placeholder. Provided text '{mmoitems' is no valid precision number.

Use ${viewer math_:_{mmoitems_stat_movement_speed}*1000}

[18:45:06 WARN]: [PlaceholderAPI] [Math] Invalid Placeholder. '{mmoitems_stat_movement_speed ' is not a valid math expression.

Expected Output:

Having the same issue myself, just with a different placeholder, but also one that recursively uses another one.

Just as a quick tip for anyone else struggling with this: A quick workaround would be to use the Shortcut expansion of PlaceholderAPI like this:

• Download the expansion using /papi ecloud download Shortcut followed by /papi reload
• There should now be a shortcuts folder in the PlaceholderAPI one. Open it.
• Create a txt file. In my example we call it example.txt
• Put the complete placeholder, including the % into the txt file (i.e. %math_{server_online}+1%)
• Save the file.
• Use shortcut_<filename> in your BTLP configuration. In our example would this be either ${viewer shortcut_example} or ${player shortcut_example}

While this sure is more effort does it allow the usage of {placeholder} patterns inside BTLP without breaking. I hope this isn't needed anymore once this has been fixed properly.
