There’s not much to making the toolbar button styles switchable: the
change to the PageTemplate introduces a new configuration tiddler that
controls the button styling. Most of this commit is the user interface
for changing that setting, including the translatable text. I think
this again demonstrates that we need to be very selective about which
configuration options have a UI included in the core. Otherwise, a few
dozen more of these settings will start to become a significant
fraction of the core.
* removed trailing whitespaces in button tids
* defined a global left margin for buttons set to 5px
* slightly less than in view-mode before
* slightly more than in edit-mode before
* but visually more appealing to me
* leaves a wee more room for the title to unfold
Reasons:
- can show or hide the button text with CSS (assuming
tv-config-toolbar-text is yes).
- can have different looking buttons in the page controls versus the
view toolbar, etc
- more flexibility styling the button appearance, for example you
can change the text size compared to the icon size
- button appearance is more themeable
