Minor bugfixes

This release has the following content:
 1) just minor bugfixes. We found some issues with colour editors/it kept erasing first character of colour definitions, and that made it
      more difficult to specify colours in the builder tool.
 2) there's new text drawing mechanism which renders text quicker with a sprite atlas. It renders from ttf file, but creates a sprite atlas that can be persistently cached and stored with the deploy files. This means the text rendering can be done quickly.
 3) draw_large_text had a crash/missing prepare() call, and we have a bugfix for this
 4) text drawing can now use special characters/it allows typing in strange characters like !?:;$£@{[]} to the text elements
 5) finnish åöä has been implemented
 6) text elements can have space(32) character in it. This was originally missing since our variadic templates use space as a separator, and we didn't have a way to separate the characters. now it uses {032} style specs for the space characters and thus allows rendering of it
 7) linux binaries are now using ubuntu 26.04 as the base => if you are using older ubuntu, you might need to upgrade to new ubuntu
     or compile via source code.
 8) bounds-checking font rendering / now it doesn't crash so easily.
 9) release-scripts were significantly improved
10) text rendering is significantly better / it doesn't mix SRGB and Linear colour spaces => now fonts are crisp and sharp.
11) new font is also available via load_font as a default
12) font engine for builder's internal text elements was changed to newer one.
