Lazier Layout, Cursor Height, First & Last Line Selections

[thecoolwinter]

Description

This is a fairly varied PR, most issues solved here don't have a related issue.

• Made line layout lazily iterate through lines. This solves:
  • Fixes a edge layout bug where lines that were not previously in the viewport aren't updated during layout. This is related to a CESE bug and is required to fix it.
  • Begins work to make minified files work w/o crashing.
• Updated the vertical selection destination to move to the beginning/end of the line if moving up/down on the first/last line.
• Made updating the textview's font cause a layout pass.
• Added docs for some public methods.
