Patch for PCManFM to remember view mode

There is a bug in PCManFM that causes it not to remember the view mode (the view mode is icons, compact, thumbnails, or detailed list). This patch fixes it.

Patch to start quick filter instead of quick search when typing in Krusader

Krusader has both quick search and quick filter, but quick filter needs to be started explicitly with Ctrl+I. With this patch, when you start typing, quick filter is started instead of quick search.

Patch to enable PCManFM quick search to match mid-string (instead of strictly at the beginning)

PCManFM lets you select a file or directory by typing the first letters of its name.

Unfortunately, it does not let you search the file by typing a sub-string that appears in the middle of the file name. For example, typing "down" will select "Downloads", but typing "loads" will not, even though "loads" appears in the string.

Luckily, there is a way to change that, but it requires patching the source code of libfm, which is used by PCManFM. So, if you have Debian, download the source code and build dependencies:

 apt-get source libfm  
 sudo apt-get build-dep libfm  

After that, apply this patch:

After that compile and install libfm:

 ./configure  
 make  
 sudo make install  

This will install it in /usr/local/lib, and our modified libfm will be loaded by PCManFM instead of the stock that comes with Ubuntu, and is in /usr/lib.
