Hopefully fixed the 'Invalid multibyte character' build error on linux (I was using left/right-angle-brackets in string constants);
Fixed 'cost' keywords;

uses correct script context for cards using a stylesheet other then the default one.

Correct styling data now shown on style panel

Problem: In src/gui/control/keyword_list.cpp and src/render/text/element.cpp, there are two characters that I cannot identify. I can't make it work, I just get the error "Invalid multibyte character.

Bug: Keywords do not register when they're in lowercase (flying vs Flying, for instance)

Correct control used for clipboard actions in CardsPanel

Added wrapping of <> around parameters to TextElement;
Added colors for keyword parameters;
Added menu & toolbar for keyword panel;
Fixed bug in package, save/save-as was the wrong way around;
Added third quality setting to RotatedDC: using SetUserScale, this gets you more precise positioning.

improved cursor motion for up/down/home/end; text editor now remembers cursor positions (instead of indices) when applying scripts.

Changed some TABs to spaces in macros, that should end the conflicts because we use different tab sizes (4 vs 8)

Fixed some bugs to make GCC work. I needed to change SimpleValueAction to take the function as a variable as opposed to a template parameter - GCC won't accept pointers from a base class in templates.
