TODO feature: Delete symbols before/after selected

Application:
V Implement "Save" menu
V Implement new saved font file format

Functionality:
V "Only numbers" range in the New dialog
V "Specify range" in the New dialog
V "Single frame", "only numbers" and "specify range" as radio buttons
V Button to Clear/Fill a block
V Copy-paste to a symbol with different size
V Change height of variable width fonts with ability to choose which side to add pixels to
V Make it possible to have zero width chars in VarWidth fonts
V Tooltips on main form

Bugs:
V Every char changes its width to default on VarWidth font height change!
V App allows to create fonts with a gap in symbol cequence!
V File -> New does not check for unsaveed changes!
V Export for symbols with 0 width in "1 per line" format has extra comma!
