Power Network Tycoon - Boost Points, Font Options and More

This update features the following changes:

• Prevented purchasing more oil than the oil storage capacity
• Added new feature. Boost Points, allowing you to start new maps with a few research tasks complete or more resources, depending on far you progressed through the game (unlocked maps).
• Added a new map GDP wealth milestone, which is at 125% of the maps score required to handover/audit to unlock the next map, serving as a reminder that you don't need to progress to 500M on the map if you don't want to (eg first map's 125% is the equivalent of 125M, then 250M for the second etc).
• Added a choice of Font. Default or Simple (Noto).
• Fixed problem with some simplified Chinese characters not being in the font file.
• Added Screenshot function (F12 key, not on Gamepad at the moment). Only works in full-screen mode.
• Small performance improvement related to updating UI text
• Corrected a 'Global Stats' string of text saying 'Most Research Completed' instead of the string 'Highest Power Draw'
