More small fixes and improvements

Changes to the Main Campaign

First, we have a few changes designed to make it easier to keep lower-level characters caught up with the rest of the team without risking their lives in the arena, and to ensure that that remains possible throughout the campaign:

• increased the availability of battle primers somewhat in the shop to make it easier to catch up underleveled characters.

• increased the range of levels where novice and intermediate battle primers are effective to keep them useful for longer.

• in the shop, intermediate battle primers are now much more likely to appear instead of novice ones once the player enters Gharial League; and once the player enters Snow Leopard League, expert battle primers are now much more likely to appear instead of novice or intermediate ones.

• added in version 1.0.51a: the game now actively checks non-Golem, non-Spirit custom characters when initiating camp and--if they're missing Practice, Clean, and Talk camp activities--adds them.

General Bug Fixes

• fixed: the game was playing drowning sound effects when checking environmental damage for destructible objects submerged in water.

• Addedfixed in version 1.0.51acustom characters were being generated without certain core camp activities available to them.

• fixed in version 1.0.51a: mind controlling an enemy minion during Psy Clash would result in the minion's attack sound effect reverting to a sword slash sound.

• fixed in version 1.0.51a: the epilogue used the word "screenplay" where "stageplay" was appropriate.

• fixed in version 1.0.51a: there was a "the" missing in one line of Malatose's dialogue during her first interrogation ("Getting straight to point now, are we").

• Fixedfixed in version 1.0.51bsome background- and trait-specific camp activities for certain custom characters were still not showing up post-hotfix.

• fixed in version 1.0.51b: portraits for certain generic characters were not loading due to a mistake in the code adding support for custom static generic character portraits.

• fixed in version 1.0.51b: a bug fix from a previous update was causing characters already present among saved characters to not get recruited during battle (most noticeably during the character sibling event in the arena).

• fixed in version 1.0.51b: skills which place multiple holds or create multiple objects at once were granting experience multiple times.

• fixed in version 1.0.51b: skills which place multiple holds or create multiple objects at once were counting multiple times for purposes of how many times the skill had been used in battle.

Campaign Creator improvements

• you can now assign your own custom static portraits to generic unit types in the character creator!

• you can now manually select skin and hair palettes for generic character portraits (and, for humans, their corresponding unit sprites) in the character creator.

• updated placeholder text in the tags field for the map editor's Unit Properties window, removing the long-since-deprecated "Add," text.

• fixed: the character creator was formatting portrait data for generic characters in such a way that their hair layer wasn't being detected upon loading them in a custom campaign.

• fixed: the character creator was not saving hair palette or skin palette data for generic characters.

• fixed: the map editor was throwing a null error when trying to create tooltips upon mousing over FromPlayerRoster character stand-ins.

Create your own campaign!

As you can see, I've been focused on fixes and improvements to the campaign creation suite. We are now just a bit more than 1/4th of the way through our campaign creation contest, and I want to make
