2. Get rid of the calls to self:fillToc() from the places in the code which cannot affect TOC.
I assume the reason for these calls is that they are needed in the original CoolReader application
(because there the TOC displays the virtual "page numbers") and were brought over to our crengine.lua
during the port.
idea is simple: when starting long operation (page renedering) invert
box on top of screen which has relative width of this page.
This allows easy overview where in document user is, along with
indication that something is still happending.
Perfect use-case are glossy magazines pdfs which have first two
pages in hi-res graphics, so this indicator is very useful to see
that something is still happending and that reader didn't die
Also, mark pagedirty in all cases when deleting the file, to cause the screen refresh --
otherwise the message "Press 'Y' to confirm" stays there indefinitely.
Since we are adding and renaming fonts, we need to make sure that
all fonts which reader uses are defined. This allows us to add fonts
and not break when users load old configuration files

1. Added parameter that tells filemanager the way how to manage files. Those who prefer 'safe' method (default) should not select any other mode except for BEGINNERS_MODE in new menu called by Alt+M. Actually, 'safe mode' is our old version (the files are filtered on the extention-basis; one may rename the filenames, but not their extentions). The tigran's corrections de0f40ce9c
are easy to switch on by selecting mode for advanced users who understand potential danger (mostly, crashes of crereader 'cause of improper input files) and accept it.
2. New menu Font:chooseFonts() to change font faces
3. Removed duplicated code of 'make screenshot'
4. The hotkeys (Back & Home) to exit FileChooser are moved down
5. Removed outdated comments
The decision whether ext:getReader(ftype) returns CREReader or nil for documents with improper file extentions now depends on the new parameter FileChooser.filemanager_expert_mode. Improper files are now related to CREReader only for advances users.
In order to switch between safe and advanced way for filechooser to manage files, I've introduced special parameter 'filemanager_expert_mode':
i) 'safe' means that filemanager shows only files with the reader-related extentions; make safe renaming (i.e. the extention remains the same)
ii) 'advanced': all files are available (no filtering); any renaming is allowed;
TODO: to add also 'expert' mode & use it for unstable or dangerous functions
