Unit tool tip fixes

[kuronekochomusuke]

• fix issues with mismatched htlm tags in the unit and pilot tool tips.
• isolate the setting of fonts in in the unit and pilot tool tips, so that it would be easier to replace them with CSS.
• fix issue with hard coded font colors in unit and pilot tool tips. use system defined ones instead.
• fix issue with the unicode characters in the movement section of unit tool tip.
• add in and <hr> around the pilot info in the board view tool tip, to make it it does not blend in with the unit info.
• fix issue when determining good critial slots, it did not include missing ones. so it was diplaying double (good and bad), when missing.
• only show the hits chance section in the attack tool tip when in the firing or physical phase. in the reporting phases only show who did it, since the hit info is no longer valid.

Overall doesn't look bad but please go through your changes and these files and adjust the variable names to be more descriptive.
